Truck parts service near Martinez, CA

Straightforward, patient and considerate of my ignorance when it comes to cars. Mostly interacted with Bruce, who was very helpful, but the small interactions I did have with the rest of the staff were just as nice. Reasonable prices and a very professional atmosphere. If you’ve got a Volvo (or Subaru I suppose), this is your place! Anna Nelson

Great people = great business and Hugh & crew at Sierra are GREAT!

007 mb e350 I have been to these guys two times and both times they handled my car and service with amazing care and detail. First time was for a service check up and their price was unbeatable by anyone within a 10 to 20 miles radius. Second time my car would not start when it was cold in the morning. So I took it to them and after having a diagnostic, turned out my crankshaft sensor was no good. They fixed and teat everything and so far the car runs amazing. Will check back within a week to see if any more problems shows up. Thanks autowerk eurpean definitely my go to guys!
