The defendant, who did not appeal from the interlocutory decree overruling the exceptions and confirming the master’s report, contends on his appeal from the final decree, that the report is not responsive to the pleadings, is confused, inconsistent, vague, contradictory and unreasonable. The bill, brought under R. L. c. 159, § 3, cl. 7, alleged, and the master finds that the defendant placed his automobile with the plaintiffs “ under a contract to repair and renovate” it, and, acting under the contract and with the knowledge and consent of the defendant, they purchased the parts necessary for replacement and furnished the labor required to make the repairs and complete the renovation of the car. It appears from the report that the defendant contended that a large part of the work had been performed in an unskilful and unsatisfactory manner after great and unreasonable delay whereby he was deprived of the use of the car, and that he never authorized the plaintiffs to have work done outside of their own shop, for which the charges, as well as the charges for their own work and for materials, were unreasonable and excessive. The issues thus raised, even if recoupment is not pleaded, were questions of fact, and the evidence is not reported. A lengthy and full review of the controversy precedes the master’s conclusions which are specifically and clearly stated in separate findings, and, after making deductions from the hours of labor as charged and for work done and for parts made and supplied outside of the plaintiffs’ shop, he establishes the defendant’s indebteáness in the amount named in the decree. If the price the defendant paid for the automobile is compared with the expense of making it over, the car finally cost him a little more than double the original outlay. It may be that during the period covered by the reconstruction he failed to realize, that by reason of the cost of labor and materials, it would have been less expensive and more advantageous to have exchanged his car than to attempt making radical and extensive changes and repairs. But he voluntarily entered into the contract, which was not to be performed for a round sum, and with constant knowledge of what was being done gave no orders at any stage to discontinue further work. The master finds that the plaintiffs’ charges were fair, reasonable and *9necessary for “the transaction of the work,” and we cannot say that this, or/any of his material findings are plainly wrong. Craig v. Warner, 216 Mass. 386. It follows that the decree should be affirmed.
