MR. JUSTICE GALEN
delivered the opinion of the court. This is an action for damages to a Studebaker automobile alleged to have occurred while such automobile was in defendánt’s possession under writ of attachment. It appears that on June 15, 1920, there was a certain action pending in the *308district court of Big Horn county, wherein E'd W. Brown, one of the defendants in the ease before us, was the plaintiff, and the plaintiffs herein, David Badboy and Nellie Bad-boy, were the defendants. On the date mentioned, the defendant herein, John MacLeod, as sheriff, seized the automobile in question on a writ of attachment regularly issued in such action, and placed the same in the charge and possession of Ed W. Brown, the plaintiff therein, and one of the defendants herein, as keeper. Thereafter, on or about November 1, 1920, while that action was still pending, the plaintiffs herein paid and satisfied all claims of the defendant herein, Ed W. Brown, against them, together with costs of suit; but the attachment on the automobile was not released or discharged. It is alleged that the defendant herein, Ed W. Brown, agreed with plaintiffs, upon settlement of such case, to dismiss the action and return the automobile to the place from which it was taken when levied upon by the sheriff, John MacLeod; but that neither of the defendants have so returned the automobile, nor have they delivered it to plaintiffs’ possession. Further, that the automobile was pulled or propelled into an open lot back of defendant Brown’s store, and there left standing unprotected, and that it has since been stripped of many of its essential parts, and damaged by the elements. Damages were asked from the defendants, in consequence, for the value of the ear alleged to amount to the sum of $1,500. Upon issue joined, the case was tried to a jury, and resulted in a verdict in favor of the plaintiffs against the defendant Ed W. Brown in the sum of $650, upon which judgment was duly entered. Thereafter the defendant Ed W. Brown made and filed his motion for a new trial, and the court, after hearing the same, made an order denying the same “providing that within 10 days therefrom plaintiff remit all damages in excess of $250, as of the date of the judgment, otherwise a new trial will be granted.” The ground for making such remission or granting a new trial is not stated in the order, but it appears from the notice of motion for a new trial that the motion was based, *309among other grounds, upon “excessive damages, appearing to have been given under the influence of passion and prejudice,” and this is the only ground upon which the order could have been predicated. The plaintiffs, having refused to remit as in the order specified, have appealed from the order granting a new trial.
They assign as error the granting of a new trial to the defendant Brown. This brings us squarely to a consideration of the evidence upon which the verdict of the jury was based, in order to determine whether the trial court abused its discretion in granting the defendant Brown a new trial.
It is admitted that the automobile was attached as alleged and turned over to the defendant Brown as keeper, and that payment was made by the plaintiffs of the amount due Brown in the attachment suit. Brown denies, however, that he agreed to return the attached automobile to the plaintiffs upon the settlement of his action against plaintiffs. This was a disputed issue of fact. The evidence shows that the plaintiffs bought the automobile in question second-hand, in August, 1919, it being a 1915 model S. D. They traded a Reo five-passenger car for it, and in February, 1920, preceding the attachment, it was in good running order. It had run about 6,000 miles before plaintiffs bought it, and they ran it but a short distance during the summer and fall of 1919. It was left in charge of one George Sherman, at Crow Agency in February, 1920, and was run into a shed for storage on its own power. The defendants immediately thereafter went to the Blackfoot Indian Agency, many miles to the northwest, and did not return until February, 1921, several months after it had been attached and placed in charge of the defendant Brown. George Sherman, who had had some experience with automobiles and as an automobile mechanic, testified that the ear at the time it was attached had “a fair cash market value” of $1,000 or possibly more; and further that at the time this action was instituted it was not worth to exceed $200. James Davidson, for the defendants, says it would take about $150 to put the *310ear in running order, but respecting Ms examination made of the car upon wMch he bases his estimate he said: “I looked over the ear, but I didn’t turn the engine over. I know if I tried I would have turned the engine over. I did not go into it to see if it might' have been stuck or the bearings burned out. They might have been, that is true. * * * I don’t know anything about that engine. I didn’t go in and examine that engine inside. * * * I never said anything about the upholstery being included in this, but he could put the upholstery in good condition. He could not put in new, but you could repair that up.”
Defendant MacLeod testified that the “market value” of the car at the time of the attachment, in his opinion, was $250, but explained: “My opinion as to the value of this ear in June, 1920, is based largely on my experiences as sheriff, in the sale of ears at forced sales.” After the demands of the defendant Brown in the attachment suit were paid in full, the plaintiffs, prior to instituting this action, in February, 1921, having returned from the Blackfoot Indian Reservation, found their car in the vacant lot back of Brown’s store, and the plaintiff Nellie Badboy, describing its condition at that time, testified: “I could tell from a glance about what was gone, but I didn’t get down in there and examine it myself. Of course, I could do that if I had to. The hood was off and the lights were off, and engine parts wore stripped, and the axle was gone, and the wheel gone. The top had been mashed in and the cushions all thrown out. This was in February. The front cushions all thrown out on the ground. Somebody, looked like, had taken a hammer and mashed all they could off of it. The windshield all mashed. I did not look around for any of the parts I have mentioned. The car wasn’t mine; I didn’t have any right to look around for the parts. The car was under attachment. I did not figure that would be a good way to sell the car to somebody. The car had not, been turned back to me.” Her testimony as to the damaged condition of the car is corroborated by other witnesses.
*311The ease was very poorly tried, much hearsay and incompetent testimony admitted, and proper eyidence excluded. The proof as to damages sustained is far from satisfactory, but there was ample before the jury to warrant the amount of the verdict. The verdict cannot be said to have been the result of passion or prejudice, and we are at a loss to know upon what ground the trial court predicated its order granting defendant Brown a new trial unless plaintiffs herein remitted all damages in excess of $250. "We cannot see where or how the court arrived at the amount of $250. It must have been purely an arbitrary amount fixed.
While it is the general rule, frequently enunciated by this [1] court, that the granting or refusing of a motion for a new trial rests in the sound legal discretion of the trial court, yet this discretion is not so unrestricted as to permit the trial court to act arbitrarily, or without substantial basis. Legal discretion must always be guided and controlled by legal principles. (Montana O. P. Co. v. Boston & M. C. & S. M. Co., 22 Mont. 159, 56 Pac. 120.) This court will not, as a rule, interfere with the discretion vested in the trial court in granting or refusing a new trial; but when it appears, as it does in this case, that such discretion has been exercised without any sufficient or substantial reason, then it must be controlled. (Holland v. Huston, 20 Mont. 84, 49 Pac. 390.) Here the abuse [2] . of discretion on the part of the trial court in granting to the defendant Brown a new trial is manifest, for there is no evidence or basis in the record for the court’s order. “Under the statute, the amount of the verdict must of necessity rest in the sound discretion of the jury. The parties are entitled to a verdict from the jury, and it is only in rare instances that the court is justified in interfering, unless the record discloses that the elements of passion and prejudice have .influenced the minds of the jurors in arriving at the result.” (Hollenback v. Stone & Webster Eng. Corp., 46 Mont. 559, 129 Pac. 1058.) The jury having fixed the amount of plaintiffs’ damages based on evidence warranting the verdict, and *312there being nothing in the record to indicate passion and prejudice, or warranting a reduction of the amount of the verdict, the trial court was clearly in error.
The order granting a new trial to the defendant Brown is reversed, and the cause remanded to the district court of Big Horn county, with directions to set it aside.
Reversed and remanded.
