wow, really clean car in all senses. I think I only had my seats out once to vacuum everything about that was about a week after I bought it. While putting the passenger seat back in I think I severly cross thread a bolt to the point where I would probably need to re-tap the sucker. Only good thing is is that I can't tighten it anymore than it is, and I can't loosen it either, no way that seat is going anywhere.
