Engine repair service near Box Canyon, CA

I have been searching for a shop for my BMW after working with some duds!!! CS Motorwerks is by far the best and most honest BMW shop to work with! I wouldn't bring my BMW anywhere else.

The best in the Valley, excellent customer service, the owner is so kind, he will take care of the customer and your car, when I need to do oil change (synthetic) I go to him, and for my tires I think I bought 3 sets of tires with him for a good price. He is the Man. -Mike D.

Robert and Ricardo went above and beyond my expectations. I wanted to compare the Yokohama and Nitto tires side by side in person so I asked if I can order both tires and decide from there. No problem with a big smile was the answer I got and they had both tires at the store within a couple of hours and installed them that same day. They drove me home and picked me up when it was all done. They had the lowest price in Valencia who had good performance tire brand and sizes I wanted in stock plus "REBATES". I went back the next day and purchased another set of Hankook tires and once again, I wasn't sure if I should get the V12 or S1s. So they ordered both for me again and I decided to go for the V12s. To be able to compare 4 sets of tires side by side and only buy 2 sets without a deposit is unheard of these days unless the shop is confident that they can sell anything and everything the customer wants to see. I will surely be back just for this reason alone. If you're picky and love premium hi-end performance tires, then this is the shop for you. They surely have all the good stuff and the shop is definitely capable. A lot of negative reviews here and yet people keep on coming. They're busy for a reason. So go figure. Don de los Reyes

Mark and all the folks at Preferred Auto are the best. Since i have had a couple German cars lately i haven't been there for a year or two. When i brought in a used Acura for them to check before i bought, they did an extremely thorough check, and though it was low miles, the car was older and needed more work than i wished to do. The charge was more than reasonable, i would have been happy even if it had been 50% higher for the work done. They are always honest and fair and look out for their customers first. They clearly know that is what has made them so successful. THE BEST! Wish they worked on German sheet metal!! Howard Kaplan

Had my 93 Chevrolet Silverado 4x4 at Performance Auto and could be happier with the service. The mechanic was polite, helpful, and very knowledgeable. The only problem I have is I'm moving to Oregon and my old girl will surely miss this shop. Kurt Devincentis

Kevin was very courteous and helpful. Very satisfied so far. Had used Gio in 2015 and was very happy with his work.
