Heh... this is the thread we should link to when young kids post about buying their first car and wonder if the old box they want to buy for 7K will be expensive to maintain!
For me - 6 months in and too many things to list. All of them have been maintenance items, and I'm soon reaching $9k. Not one fun mod yet... any my car was in excellent condition when I got it. Partly I've gone overboard with the preventative stuff, and partly its expensive to buy parts in Europe with the high sales tax and markup. The car runs great though and I love it!
