OPINION
OGG, Judge.This matter comes before us as a test case to determine the lien rights of a towing operator who is called by a deputy sheriff to an accident scene to remove a disabled automobile after the injured owner has been taken unconscious to a hospital.
On January 2, 1969 a deputy sheriff, in the process of investigating a traffic acci*31dent, called the defendant Fields — who operated a towing service — to remove the disabled automobile belonging to plaintiff Steyaert. Fields towed Steyaert’s automobile to his garage premises where it was stored. Approximately a month later the plaintiff’s wife and a representative of plaintiff’s insurance carrier, State Farm Mutual Insurance Company, demanded the return of the automobile which was refused by Fields when the parties could not agree on the amount of storage charges. On February 13, 1969 Steyaert sued in replevin to recover possession of his automobile or, in the alternative, for damages. Fields counterclaimed for his towing and storage charges. During the ensuing months and before the trial Fields sold the automobile as an abandoned vehicle pursuant to A.R.S. § 28-1405, subd. B. At the trial the court awarded Steyaert the sum of $150.00 and dismissed Fields’ counterclaim. Fields now brings the appeal from that judgment.
Under the facts of this case: Does a garageman have a lien for storage charges that can be enforced by a sale when the automobile is in his possession at the direction of a police officer without the knowledge or consent of the owner? We believe not. The legislature has enacted specific legislation that covers this question in A.R.S. § 33-1022, subd. B:
“Proprietors of garages, repair and service stations shall have a lien upon motor vehicles of every kind, and the parts and accessories placed thereon, for labor, materials, supplies and storage for the amount of the charges, when the amount of the charges is agreed to by the proprietor and the owner." [Emphasis added]
No one contends that there was ever an agreement between Fields and Steyaert or any of their representatives as to what the proper amount of charges were to be and therefore Fields’ contention that he had a valid lien under this statute must fall.
Fields’ position in this case is made further untenable by his treatment of the automobile as “abandoned” and his subsequent sale under the Arizona statute relative to abandoned vehicles. A.R.S. § 28-1401 et seq. Obviously this was not an abandoned automobile; once Steyaert was informed of the location of his automobile he made a demand for possession.
Appellant Fields makes a strong policy argument that a garageman will never again answer an officer’s call to clear the wreckage from our public highways unless he is granted a lien.
Appellee Steyaert makes an equally compelling argument that a motorist rendered unconscious in an accident should not awaken to find his automobile has been towed away, stored and eventually sold unless he pays an exorbitant bill that was not of his own. making. These impassioned policy arguments make good reading but are considerations for the legislature and not for the courts.
The statute covering this situation is unambiguous. We must presume that the legislature, with sound reasoning, meant what it said and that no garageman shall have a lien in such a case unless the amount of the charges is agreed to by the owner of the automobile.
We believe the legislative intent to be that the owner or his agent must have placed the automobile with the garageman and made some express or implied contract relative to the charges to be incurred before the garageman can have a lien on the automobile.
We have two principal Arizona cases bearing upon the issue in this casé. In Fishback v. Foster, 23 Ariz. 206, 202 P. 806 (1922), the Arizona Supreme Court reversed a trial court decision that permitted a garageman to sell a car to collect an unpaid storage bill on a car that had been placed in storage by the owner. The court held that, although the garageman had no statutory lien under the existing laws, he did have a common-law warehouseman’s lien; he could retain possession of the automobile as security for the debt but this did not include the right to sell the auto*32mobile to satisfy the lien. The common-law lien granted in that case has now been covered by the provisions of A.R.S. § 33-1022, subd. B.
In Bayham v. Fields, 10 Ariz.App. 7, 455 P.2d 294 (1969), the Arizona Court of Appeals, in a case interpreting A.R.S. § 33-1022, subd. B, upheld a decision of the trial court awarding storage charges to a ga-rageman for storing a trailer pursuant to a sheriff’s attachment. The appellate court in that case stated by implication it would have reversed the trial court on the ground that the owner of the trailer never consented to the amount of the storage charges; however, since this issue was never raised in the trial court and there was an inadequate record, it affirmed the order of the trial court.
In the instant case, Fields also contends that the trial court erred in not granting a judgment in his favor at the end of plaintiff Steyaert’s case. The record does not support this contention. Steyaert established that Fields was in possession of the automobile and that Fields had refused to surrender possession upon demand. Whether Fields was justified in so refusing was avoidance matter which he had the burden of proving in the form of an affirmative defense. Arizona Rules of Civil Procedure 8(d), 16 A.R.S.; Lakin Cattle Co. v. Engelthaler, 101 Ariz. 282, 419 P.2d 66 (1966).
The record discloses that there was no dispute at the time of trial relative to the fact that Fields was entitled to a reasonable sum for his tow bill and storage charges incurred prior to the date of demand for the return of the automobilé. The accrued tow and storage charges at that time amounted to a total sum of $97.-1.6.
We hereby modify the judgment in this case to award the appellant Fields the sum of $97.16 on his counterclaim against Stey-aert.
The judgment of the trial court is affirmed as modified.
