Diagnostic services service near Chatsworth, CA

This is one place on where I will be a FOREVER Customer and Loyal at that. Today I had the wrose most horrible day dealing with a set of bad companies that deal with tires. I was out and about for almost 8 hours trying to get my tires replaced due to one of them having a Bad Factory tear on the inside of the tire. I got here at 6:45pm, right before they closed and this AMAZING WONDERFUL Gentleman asked me how I was doing and was super sweet to hear what happened. He said he was sorry for what happened and that he would be happy to help. Within minutes of getting there, the guys out in the garage did the alignment, changed out all 4 tires and also told me that I had 2 other problems with the Tire area and helped me in every way to get my car back on the road safe for me to drive. It took these gentlemen 40 min.s to get it all done right. They helped me with everything, got me a warranty on the tires and more. I couldn't have been anymore happier, they made my day better. Thank you guys for the help and can't wait to come back to get more service done on my car. Krystel Carrilo

I'm not the most technical person when it comes to auto knowledge but the work was done quickly and part was ready when I got there. What Amenities...?

if you are looking for a fast, honest, friendly service then Mr. Smog Test Only is the place to be. i was in and out in 15 min. and the certificat was sent to the DMV, and they will have auto regestration soon so it makes it more convenient to get SMOG AND TAGS at one place.

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.

Please remove this place from any shop in LA horrible niggle be stealing everyones cars lol !!!! CROOK ALERT

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

Sami is the best. When I got locked out of my Benz, he got it open, made new locks and keys and didn't charge the crazy prices my AutoClub membership would have. He knows cars. Glad I know Sami. -Liz Sherman Oaks
