I would definitely go back to Rolf's Import Auto Service. Their customer service and honesty was great. I took my car there the first time because it stalled on the freeway. They were honest with me that it had just run out of gas. They worked on my Mercedes for some kind of an engine issue and that was quite reasonably priced. Then they did my brakes as well. I've been there a lot and I've sent family members there as well. They're an honest shop with comparable prices.
