i had some good experiences with my dealer about 2 weeks ago. my car was in an accident a few months after i got it, and i've done a few mods since then including mbc, fmic, cai, midpipe, and boost gauge (a few others but you get the point). i had something wrong with something in the suspension and the dealer fixed it under warranty. i also have a CEL and the guy was real cool about it, he read the code for free and told me its no big deal, everything was ok, but i'd have to change some things before my next inspection. This was in Tysons Corner virginia, with a guy named Bill.
