I recommend Westcoast Automotive in Santa Rosa highly. They are an honest dealership that does quality work and superb customer service.I found the shop on line looking for custom work of having my car insulated against road noise. I have a significant hearing challenge and it is naturally frustrating to my wife or passengers when I cannot hear them. I could not find anyone in the East Bay with experience or interest in doing the work. I called up and talked with Greg, who is the owner. He checked with Mike, his master mechanic who had done this type of work previously. Greg then said he wanted to research this project to get the best possible materials !! He called me back a few days later and told he he was special ordering the material that was the best quality for this job. I scheduled the work. It took Mike three days to do this job, which was more challenging than originally anticipated. Regardless, they still honored the original estimate. They did a wonderful job and certainly made me and my wife happy and devoted fans. This is one great shop and I only wish I lived closer so I could have all my auto work done there
