Aww man, I'd be annoyed too if I found out this happened. Sucks cos it tarnishes the whole experience but IMO I think it's how the dealer resolves the issue that will be the true experience. As long as they take care of things for you and take care of you I think the experience is still positive.
Manufacturing defects will always fall through cos no place is 100% but it's how they deal with it that shows true service.
I would be concerned though, at the rust in the seat hinges and other areas that were mentioned in the other thread though... how does that happen to a brand new car?
