I found rsw through the apr website. it is a certified apr dealer. so far the relationship is good, no complaints. they had a free coupon for a complete vehicle diagnostics. the entire shop from what I can see is very clean, including the bathroom. they fixed an exhaust problem I was having, and I just got a apr stage 1 tune today. I would definitely recommend this shop. I didn't give a five star, because I've only been dealing with rsw for about three weeks. I also believe everyone has room for growth.
