First time to bring my BMW Z4 to Performance Autowerks, after doing some research online. Can say I agree with all the reviews I have read. Rich was very helpful and immediately ran a diagnostics on my car, which showed I needed a new water pump. He explained what needed to be done, gave me a quick quote on all the parts and work involved and told me he can have it done in a couple of days, which was fine with me. That's why I was really surpised when I got a call from them about 5pm that same day telling me they were able to finish my car! All in all I am really satisfied with the work.
