This appeal requires us to revisit the constitutional propriety of a state’s Sunday closing laws. Appellant Kittery Motorcycle, Inc. (“Kittery”) is a motorcycle dealership located in Kittery, Maine, near the New Hampshire border. Kittery claims that Maine’s Sunday closing laws, Me.Rev. Stat. Ann. tit. 17, §§ 3203-3204 (West Supp.2002), violate the United States Constitution’s guarantees of equal protection and due process because, as a result of numerous exemptions enacted ovеr the past half century, these laws authorize the sale of everything on Sundays except motor vehicles (defined to include motorcycles under Maine law). Kittery claims that, as a consequence, it loses substantial business to dealerships in New Hampshire, a state that permits the sale of motorcycles on Sunday.
*45 While Sunday closing laws may be vestiges of a bygone era, we conclude that the laws at issue are not constitutionally infirm. Just as the district court rejected Kittery’s challenge to Maine’s Sunday closing laws, so do we.
I.
A. Maine’s Sunday Closing Laws
Maine’s general Sunday closing law opens with the following pronouncement: “No person, firm or corporation may, on the Lord’s Day ... keep open a place of business to the public, except for works of necessity, emergency or charity.” 1 Me. Rev.Stat. Ann. tit. 17, § 3204 (West Supp. 2002). The statute is criminal in nature. First-time offenders “shall be punished by a fíne of not more than $100 or by imprisonment for 30 days, or by both.” Id. The penalties increase substantially for repeat offenders. Id.
Over the years, the Maine legislature has exempted dozens of different businesses from the law’s application. As of 2002, the law exempted such diverse businesses as seasonal dairy stands, ship chan-dleries, textile plants, bowling alleys, and real estate brokers. Id. Another exemption applies to retail stores that employ no more than five persons. Id. Likewise, retail stores that have “no more than 5000 square feet of interior customer selling space” may opеn on Sundays. Id. Finally, a 1990 amendment carved out an exemption that practically swallowed the rule'— retail stores larger than 5000 square feet may open on Sundays provided that they do not require their employees to work that day. 2 Id.
However, section 3203 is explicit in its prohibition of motor vehicle sales:
Except as provided in section 3203-A, 3 any person who carries on or engages in the business of buying, selling, exchanging, dealing 'or trading in new or used motor vehicles; or who opens any place оf business or lot in which that person attempts to or does engage in the business of buying, selling, exchanging, dealing or trading in new or used motor vehicles; or who does buy, sell, exchange, deal or trade in new or used motor vehicles as a business on the first day of the week, commonly known and designated as Sunday, is a disorderly person.
Me.Rev.Stat. Ann. tit. 17, § 3203 (West Supp.2002). Under Maine law, a motorcycle is considered a “motor vehicle.” Me. Rev.Stat. Ann. tit. 29-A, § 101(38) (West 1996 & Supp.2002). A person convicted of violating section 3203 is subject to a fine of no more than $100, imprisonment for not more than ten days, or both. Me.Rev.Stat. Ann. tit. 17, § 3203 (West Supp.2002). As with section 3204, the penalties increase substantially for repeat offenders. See id. § 3203 (“[T]he 3rd or each subsequent offense must be punished by a fine of not more than $750 or by imprisonment for not more than 6 months, or by both.”).
B. Proceedings Below
Kittery filed suit in the United States District Court for the District of Maine on *46 August 10, 2001, seeking a declaratory judgment that sections 3203 and 3204 are “unconstitutional to the extent thеy prohibit motorcycle dealers from selling motorcycles in Maine on Sundays.” In the alternative, Kittery sought a declaration that its dealership could legally operate on Sundays pursuant to the 1990 amendment to section 3204 (the exemption for retail stores larger than 5000 square feet).
Following limited discovery, both sides moved for summary judgment. Kittery assailed the closing laws on a number of fronts. First, it argued that sections 3203 and 3204 violate the United States Constitution’s guarantees of еqual protection and due process in that they single out motor vehicle dealerships for closure while permitting every other business to remain open on Sundays. Next Kittery argued that, assuming arguendo that the state could constitutionally proscribe Sunday motor vehicle sales, the state had no rational basis for classifying motorcycles as “motor vehicles.” Kittery maintained that motorcycles are more akin to recreational vehicles' — such as all-terrain vehicles and snowmobiles — whose sale on Sundays is not proscribed. Finally, Kittery argued that sections 3203 and 3204 are unconstitutionally vague and that the 1990 amendment to section 3204 impliedly repealed section 3203.
In a thoughtful opinion, the district court expressed frustration with the seemingly “illogical” nature of the statutory scheme. Ultimately, however, the district court held that Kittery’s arguments must fail in light of the constitutional presumption that “absent some reason to infer antipathy, ... judicial intervention is generally unwarranted no matter how unwisely we may think a political branch has acted.”

A. The Equal Protection and Due Process Claims
As explained above, Kittery claims that Mаine’s Sunday closing laws violate constitutional guarantees of equal protection and substantive due process.
4
In making its claims, Kittery does not argue that an equal protection analysis differs in any way from a due process analysis. Indeed, the parties have, by and large, framed their arguments almost solely in terms of equal protection. Accordingly, we will analyze Kittery’s claims solely in terms of equal protection.
See Minnesota v. Clover Leaf Creamery Co.,
*47
The Supreme Court has developed a tripartite rubric for evaluating equal protection challenges to legislation. When a statute burdens certain “fundamental rights”—e.g., voting rights or the right to interstate travel—a reviewing court will strictly scrutinize that statute, upholding it only if the government can clearly demonstrate a compelling interest incapable of being served by less intrusive means.
See, e.g., Atty. Gen. of N.Y. v. Soto-Lopez,
All other regulations, including the statute under review in this case, are subject to the third and least exacting tier of scrutiny—rational basis: “Social and economic legislation ... that does not employ suspect classifications or impinge on fundamental rights must be upheld ... when the legislative means are rationally related to a legitimate government purpose.”
Hodel v. Indiana,
Kittery faces an uphill battle. Under the rational basis tеst, the classifications in Maine’s Sunday closing laws “come[ ] to us bearing a strong presumption of validity,”
Beach Communications,
Kittery first attacks the Sunday closing laws as they apply to motor vehicle dealerships, asserting that the myriad accumulated exceptions to the laws “have rendered the scheme arbitrary and illogical.” Thus, according to Kittery, the closing laws “no longer bear a rational relation

ship to the statute’s purported purpose[ ],” the promotion of Sunday as a day of rest and relaxation. We soundly rejected an identical argument in
Montalvo-Huertas.
In that case, a convenience store owner filed suit in the district court in Puerto Rico, challenging the commonwealth’s Sunday closing laws as unconstitutional.
Montalvo-Huertas,
the legislature need not approach goals on an all-or-nothing basis: “reform may take one step at a time, addressing itself to the phase of the problem which seems most acute to the legislative mind.... The legislature may select one phase of one field and apply a remedy there, neglecting the others.”
Id.

Williamson v. Lee Optical Inc.,
Apparently recognizing the precedential hurdle of Montalvo-Huertas, Kittery does not argue that each and every one of section 3204’s listed exemptions fails to have a rational basis. Nor does Kittery argue that the promotion of Sunday as a day of rest is an illegitimate government purpose. Rather, Kittery tries to circumvent Mon-talvo-Huertas by arguing that Maine’s Sunday closing laws, in effect, single out motor vehiсle sales for prohibition. Kit-tery points out that the provisions of sections 3203 and 3204, read together, permit any retail business to open on Sundays except for motor vehicle dealerships. See Me.Rev.Stat. Ann. tit. 17, §§ 3203-3204 (West Supp.2002). This singling out of motor vehicle sales, according to Kittery, is utterly irrational. 6 In reply, the state claims that the legislature could have reasonably assumed that sales commissions form a substantial portion of the compen *49 sation of most motor vehicle salespersons. The legislature could have therefore reasonably concluded that motor vehicle salespersons would feel compelled to work on Sundays in order to earn commissions, regardless of whether their employers actually required them to work, thereby undermining the state’s legitimate goal of promoting Sunday as a day of rest. Kit-tery responds by pointing out that real estate brokers and motor home salespersons can work on Sundays, see Me.Rev. Stat. Ann. tit. 17, §§ 3203-A, 3204 (West Supp.2002), even though they typically work on a commission basis. Thus, Kit-tery maintains, it is arbitrary and irrational for the state to treat motor vehicle dealers any differently.
The difficulty with Kittery’s response is twofold. First, it assumes that there must be a precise, mathematical fit between the classification and the legitimate government purpose the classification serves—an altogether insupportable assumption given the unexacting nature of rational basis review.
See Dukes,
In addition to challenging the state’s decision to treat motor vehicle dealerships differently from other retail establishments, Kittery also challenges the *50 state’s decision to classify motorcycles as motor vehicles. 10 See Me.Rev.Stat. Ann. tit. 29-A, § 101(38) (West 1996 & Supp. 2002). According to Kittery, “motorcycles are recreational vehicles, and as such are similarly situated with other recreational vehicles and equipment that can be sold on Sundays.” Hence, Kittery maintains, the legislature’s decision to classify motorcycles as motor vehicles is “arbitrary and irrational.” We disagree.
In its brief, Kittery states that, “[i]n Maine, one purchases a motorcycle not as a mode of transportation, but as a form of recreation akin to snowmobiles, boats, motor homes, jet skis, or all-terrain vehicles.” In supрort of this pronouncement, Kittery points us to affidavits and deposition testimony of Kittery’s vice-president and its general manager. With all due respect to Kittery and its staff, reasonable minds can differ, and the legislature could have reasonably concluded that, weather permitting, many people in Maine would use motorcycles as a mode of general transportation (for example, to go to and from work or school). And the legislature could have just as reasonably concluded that not many people in Maine would use snowmobiles, boats, motor homes, jet skis, or all-terrain vehicles for such routine transportation purposes. Buttressing this conclusion is the fact that motorcycles, like other motor vehicles, can be operated on roads and highways, whereas all-terrain vehicles and snowmobiles cannot. See Me.Rev.Stat. Ann. tit. 12, §§ 7827, 7857 (West 1994 & Supp.2002). Similarly, motorcycle operators, like motor vehicle operаtors, must be licensed, whereas operators of all-terrain vehicles and snowmobiles need not. Id. §§ 7823, 7853.
In sum, we are not led to the inescapable conclusion that the legislature acted irrationally when it chose to classify motorcycles as motor vehicles rather than recreational vehicles. We agree with the observation of amicus that “[n]o doubt, the Legislature could have treated motorcycles the way it treats recreational (off rоad) vehicles for Sundays sales purposes.” To Kittery’s detriment, however, the legislature chose not to, and we will not disturb that decision.
B. Kittery’s Other Arguments
Before the district court, Kittery advanced two other arguments—that sections 3203 and 3204 are unconstitutionally vague, and that the 1990 amendment to section 3204 impliedly repealed section 3203. The district court, finding that Kit-tery was “wrong and so clearly wrong on these issues,” disposed of these arguments in a footnote.
Kittery Motorcycle,
First, as for the void-for-vagueness argument, the Due Process Clause of the Fourteenth Amendment “requires that statutes or regulations be sufficiently specific to provide fair notice of what they proscribe.”
Brasslett v. Cota,
Kittery alsо argues that the prohibitions of section 3203 were impliedly repealed by the 1990 amendment to section 3204. We reject this argument as well. “Courts do not lightly assume that one statute has implicitly repealed another.”
Greenless v. Almond,
Given our reluctance to find an implied repeal, if we can reasonably read the two statutes consonantly, we will.
See Rhode Island v. Narragansett Indian Tribe,
III.
For the foregoing reasons, the judgment of the district court is AFFIRMED. Costs to appellee.
It is so ordered.

Montalvo-Huertas,
.
Kittery does not allege any animus or improper motive on the part of the legislature in singling out motor vehicle dealerships.
See Romer v. Evans,
. In contrast, one need only drive past the dealership's fixed location to determine whether the closing law is being violated.
. The state quotes much of the legislative history in support of its proffered justifications. While we appreciate the thoroughness of the state’s brief, we feel obliged to- point out that, under rational basis review, it is " 'constitutionally irrelevant [what] reasoning in faсt underlay the legislative decision.' "
U.S. R.R. Retirement Bd. v. Fritz,
.The state also claims that the Sunday closing laws are rationally related to other legitimate state interests—e.g., reducing overhead costs in an inelastic market and providing a day in which consumers can browse without being bothered by salespersons. Having determined that the closing laws are rationally related to the state's legitimate interest in the promotion of Sunday as a day of rest, we need not consider these other arguments.
. " 'Motorcycle' means a motor vehicle that has a seat or a saddle for the use of the rider and is designed to travel with not more than 3 wheels in ground contact.” Me.Rev.Stat. Ann. tit. 29-A, § 101(38) (West 1996 & Supp.2002).
. The record reflects that this is precisely what the plaintiff has done in the past—remain open on Sundays for the sale of other merchandise, but not motorcycles.
. Although the statutory provisions themselves refute any argument for implied repeal, we note that the lеgislative activity subsequent to the 1990 amendment confirms the unmistakable import of the statutes. In 1995 the Maine Legislature refused to enact a bill which would have expressly repealed section 3203, see An Act to Permit Motor Vehicle Dealerships to Operate on Sundays, L.D. 109, 117th Leg., 1st Sess. (Me.1995) (unenacted), and in 2001 refused to enact a bill which would have exempted the sale of motorcycles from section 3203, see An Act to Permit the Sale of Motorcycles on Sunday, L.D. 68, 120th Leg., 1st Sess. (Me.2001) (unenacted). The floor debates around this latter bill—whiсh was cosponsored by Kittery's representative on Kittery's behalf—make clear that no one thought that the 1990 amendment had impliedly repealed section 3203. See 120 Me. Leg-is. Rec. H-489 (Apr. 25, 2001) ("As it is, six days [of the week] you are able to buy the motorcycle.”) (statement of Rep. Thomas); id. H-491 ("I guess I just can't understand why we, as a government, have to hang on to this one little vestige of what somebody called the blue laws and not allow this one individual [Kittery] to stay open and run his business and try to make a sale or two.”) (statement of Rep. Morrison).
