I don't know WTF (pardon my language) is going on with these dealers in Michigan. When I first bought my car (CPO), the heated seat wasn't working so I took it to a dealer I no longer go to, and while they were removing the seat, they dropped it on the sill and B-pillar, tore through the factory labels and put a big gash next to the sill cover. Didn't bother to tell me, just patched the scratches with some purple anti-corrosive paint and sent me on my way. When I complained, they owned up to it and sent it to a paint shop. At the same time, they were supposed to adjust my quarter glass. They gave it to some young punk who made three attempts to fix it.
First, they called me to the dealership, telling me my car would be ready. I spent an hour waiting until the closing time, only to find out the guy was unable to adjust the driver-side door glass in time, so they weren't able to release the car to me. Fine, I waited till Monday, same thing, at 5:30 PM, the service manager comes to me, and tells me they can't adjust the quarter glass. I talk to the mechanic and he tells me he doesn't know what's going on, there is "nothin' but two bolts to adjust" and everytime he does, it gets out of whack again (the two bolts were the the clamp bolts that hold the glass). I am pissed by this time so I go online and I find a TSB on Billsden.org, describing a lot more than just two bolts to adjust (angle, height stop etc). I call the dealer the next day and they tell me there's probably something wrong with my roof and they were ready to send it to a body shop to work on it, but not before they would "consult a dealer in Chicago" to see what the problem could be. I wait another two days, no call from the dealership, and now I'm really mad. So I drive over on Wednesday, determined to pick it up, whether it's ready or not. I show up around five, a half-hour before closing, and the SA is clearly surprised to see me: "Did I call you earlier? They're just wrapping it up." No, you DID NOT CALL me, can I talk to the mechanic? I go over to see the technician, it's the same young guy who was working on my car before. I'm polite with him, ask him what the problem was, because I want him to open up. He goes, 'Yeah there's a lot of adjustments, angle, this and that." I say, thanks, storm over to the service desk and just unload on the manager. He's trying to tell it's not that simple, there's a lot to adjust and I interrupt him, " I know, I've read the TSB, here's a copy of it for your next customer!" The quarter glass got out of alignment within about a week and I called the MB customer service and they hooked me up with with my current dealership where they just replaced the whole quarter glass mechanism and I haven't had a problem since, until now (with the dent and broken clip, not the glass).
Oh, and I forgot to mention the previous dealership's work on my old SLK230 - they cracked the engine cover, and right after my warranty expired, they found $2,800's worth of repairs, including a leaky differential (at 34,000 miles). Funny thing, I never noticed any fluid on my garage floor until AFTER they fixed it! Then, I found a puddle of yellowish differential fluid on my floor, and had to take it back. They blamed it on the "extreme cold" at the time, which caused it not to seal properly. So, here's my story, tell me if this is normal, 'cause I'm about ready to get a Honda!
