OPINION
Daniel Castaneda, Jr. appeals his conviction for burglary of a habitation, enhanced by two prior felony convictions. Appellant pleaded not guilty, was tried before a jury, and was found guilty. Appellant entered pleas of true to both enhancement paragraphs, the court found both paragraphs true, and it assessed punishment at confinement for thirty years. In six issues, appellant generally contends (1) he received ineffective assistance of counsel and (2) his punishment violated the cruel and unusual punishment clause of the Eighth Amendment. We affirm the trial court’s judgment.
Background
Appellant went with another man to the Ivy Apartments on November 29, 2001. The other man kicked in the door to Ivonne Pedroza’s apartment while appellant acted as the lookout. Appellant fol *721 lowed the other man into the apartment, and they took a television and video cassette recorder. Shortly thereafter, appellant approached maintenance workers in the apartment complex. Appellant had the stolen property in a cloth bag or sheet, showed it to the workers, and tried to sell it to them. While still holding the bag, appellant then approached one of the residents, had a conversation with her, and left her presence no longer carrying the bag. Edgar Huerta, one of the maintenance workers, saw this occur and suggested to the resident she take the television and video cassette recorder to the apartment office. The items were turned in to the office and returned to Ms. Pedroza.
Ineffective Assistance of Counsel
In his first, second, and third issues, appellant contends he was denied effective assistance of counsel at trial due to counsel’s unfamiliarity with appellant’s indictment and Texas law. More specifically, appellant complains his counsel instigated an implausible trial strategy, failed to familiarize himself with a common-law exception to rule 609(b), and failed to familiarize himself with appellant’s record and the State’s notices of extraneous offenses. Appellant moved for a new trial and stated the basis of his motion was that “the verdict is contrary to the law and the evidence.” The court overruled appellant’s motion.
A strong presumption exists that counsel is competent.
Bone v. State,
An appellant has the burden of showing ineffective assistance of counsel by a preponderance of the evidence.
Thompson v. State,
Appellant bases his complaint on counsel’s objection to the admission of a prior burglary of a vehicle conviction. Accord *722 ing to appellant, counsel did not understand that the burglary of a vehicle conviction was admissible for impeachment, leading appellant to agree to testify under the assumption the conviction would not be admitted. Appellant argues counsel’s objection to the admission of the conviction shows an implausible trial strategy, unfamiliarity with the common-law exception to rule 609(b), and unfamiliarity with appellant’s record and the State’s notices of extraneous offenses.
Before trial, the State notified appellant of its intent to introduce evidence of appellant’s prior convictions, including the 1989 burglary of a vehicle. Before appellant testified, the following exchange took place:
COURT: All right. Mr. Castaneda— are there also other offenses that would be used to impeach him?
DEFENSE COUNSEL: Yes, sir. Mr. Castaneda understands there’s two paragraphs in this indictment and he understands that he can be impeached with the delivery of a controlled substance offense and also burglary of a vehicle offense that’s set out in his indictment.
THE COURT: Mr. Castaneda, you understand that if you choose to testify, you can be questioned about your pri- or convictions and that could have an influence upon the jury? That’s a chance you’re gonna take?
DEFENDANT: That’s a chance I’m taking.
THE COURT: You’re fully aware of that could very likely occur?
DEFENDANT: Yes, sir.
As noted above, counsel referred to the burglary of a vehicle conviction listed in appellant’s indictment. After the above exchange, though, appellant’s counsel objected to the admissibility of the burglary of a vehicle offense because the offense occurred more than ten years earlier. See Tex.R. Evid. 609(b).
Appellant does not appeal the admission of the conviction. He recognizes the exceptions to rule 609(b), allowing for admissibility of the 1989 burglary of a vehicle conviction.
See
Tex.R. Evid. 609(b) (allowing for admission of conviction if “the court determines, in the interests of justice, that the probative value ... substantially outweighs its prejudicial effect”);
Lucas v. State,
Contrary to appellant’s argument, however, the exchange between appellant and the court clearly shows appellant was aware of the possibility the burglary of a vehicle conviction could be used to impeach him, and “that’s a chance” he took. Moreover, even without the above exchange, appellant fails to meet his burden of showing ineffective assistance of counsel. Appellant argues counsel gave him erroneous advice. The record does not support appellant’s allegation. Nothing in the record reveals counsel’s advice to appellant regarding the admissibility of the burglary of a vehicle conviction. Such a silent record cannot overcome the strong presumption of reasonable assistance of counsel.
See Thompson,
Even if appellant made a showing that counsel’s representation was deficient, appellant has not shown any prejudice to his defense. Appellant’s only argument is
*723
that “[n]o doubt he would have been given the minimum, twenty-five years, had he ... pleaded guilty before the court.” Other than appellant’s assumption, though, he has not shown any probability that sufficiently weakens our confidence in the trial or its outcome had he either not testified or not elected to have a jury trial.
See Cardenas,
We conclude appellant has not made a showing of deficient performance or sufficient prejudice. Other than his statements in his brief, which are not supported by the record, appellant has not shown that counsel was ineffective or that the results of the proceeding would have been different.
See Strickland,
CRUEL and Unusual Punishment: Eighth Amendment Violation
In his fourth, fifth, and sixth issues on appeal, appellant argues his punishment violates the cruel and unusual punishment clause of the Eighth Amendment. Appellant specifically claims the punishment is not proportionate to his offense because of the lack of gravity of the offense and the harshness of the punishment. He also argues the sentence is disproportionate to that of other criminals in the same and different jurisdictions. Appellant, however, has waived this complaint.
For error to be preserved for appeal, the record must show appellant made a timely request, objection, or motion. See Tex.R.App. P. 33.1(a)(1). Constitutional rights, including the right to be free from cruel and unusual punishment, may be waived.
Rhoades v. State,
Notwithstanding appellant’s failure to preserve error, however, his argument fails. Punishment assessed within the statutory range is not unconstitutionally cruel and unusual.
Kirk v. State,
Appellant argues that because burglary of a vehicle is now a class A misdemeanor we should consider his punishment as if not enhanced with that felony.
See
Tex. Pen.Code Ann. § 30.04(d) (Vernon 2003). However, appellant was convicted in 1989, and at that time, burglary of a vehicle was a third-degree felony.
See
Act of May 23, 63d Leg., R.S., ch. 399, § 30.04,-1973 Tex. Gen. Laws 883, 927,
amended by
Act of May 29, 1993, 73d Leg., R.S.,. ch. 900, § 1.01, 1993 Tex. Gen. Laws 3586, 3634. When the legislature changed burglary of a vehicle to a misdemeanor, it provided that an offense committed before the effective date of that amendment — September 1, 1994 — is governed by the law in effect when the offense was committed, in this case, the law stating burglary of a vehicle was a felony.
See
Act of May 29, 1993, 73d Leg., R.S., ch. 900, §§ 1.01, 1.18, 1993 Tex. Gen. Laws 3586, 3634, 3705 (amended 1999). Because appellant committed the offense of burglary of a vehicle prior to September 1, 1994, his burglary of a vehicle conviction was appropriately used as a felony-enhancement for section 12.42(d) of the penal code.
See
Tex. Pen.Code Ann. § 12.42(d) (Vernon 2003);
see also Wilson v. State,
Moreover, even if we did not consider appellant’s prior burglary of a vehicle conviction, his argument still fails. Appellant pleaded true to the enhancement paragraph alleging he had been previously convicted of the felony offense of delivery of a controlled substance. As long as the punishment is within the range prescribed by the legislature in a valid statute, the punishment is not excessive, cruel, or unusual.
See, e.g., Jordan v. State,
Appellant also argues, though, that even if punishment is within the statutory range, it may not survive under the Eighth Amendment if the punishment was grossly disproportionate to the offense. In
Jackson v. State,
the Texarkana court recognized that a prohibition against grossly disproportionate punishment survives under the Eighth Amendment apart from any consideration of whether or not the punishment assessed was within the statutory range.
Even if we were to meet the threshold comparison and determine the gravity of the offense was disproportionate to the sentence, appellant has presented nothing for comparison, specifically sentences for other persons convicted of burglary of a habitation enhanced by two prior felonies. As we stated above, when appellant committed the burglary of a vehicle offense, it was a felony. See Act of May 23, 63d *725 Leg., R.S., ch. 399, § 30.04, 1973 Tex. Gen. Laws 883, 927, amended by Act of May 29, 1993, 73d Leg., R.S., ch. 900, § 1.01, 1993 Tex. Gen. Laws 3586, 3634. The amendment to the penal code clearly states an offense committed before the amendment was effective is governed by the law in effect when the offense was committed. See Act of May 29, 1993, 73d Leg., R.S., ch. 900, § 1.18, 1993 Tex. Gen. Laws 3586, 3705. Accordingly, appellant’s arguments addressing persons convicted of a misdemeanor as an enhancement are irrelevant because the arguments do not compare sentences of persons who committed the same offense — that of burglary of a habitation enhanced by two prior felonies.
Appellant did not preserve his constitutional complaint regarding the Eighth Amendment. Even if he had preserved it, though, appellant’s argument fails because his punishment fell within the statutory range. Appellant does not present sufficient argument that his sentence was disproportionate to sentences received by defendants who committed the same offense in this or other jurisdictions. We resolve issues four, five, and six against appellant.
We affirm the trial court’s judgment.
Notes
. Appellant’s motion for new trial merely alleges "the verdict is contrary to the law and the evidence.”
