So I had gotten quite a lengthy bill of "recommended" fixes from the dealer so I sought a second opinion at Cam's after consulting with Yelp. Since I live around the corner I figured what the heck? So I brought my car in and the mechanic walked me through what they found. What I came away with was totally unbiased, no-pressure technical advice that has given me tremendous peace of mind. They didn't even charge me for the estimate. So while there's nothing actually wrong with my car at the moment, I know where I'll be taking it the next time there is. Thanks Cam!
