Forget replacing the tires - you will NOT get what you paid for them. The dealer I bought mine from threw on new Continentals which I HATE, but dealers pay wholesale for them, so that's what they do.

I sold my Prelude last year on Cars.com, which cross-lists to msn autos and a few other used-car listings on the net. I think $50 gets you an ad with pictures for a month. I got a lot of action from that listing.

Just make sure to list it for $500 to $1000 more than you really want to get, because everyone looks at cars $500 to $1000 more expensive than they can afford to buy, hoping that they can talk you down that much.
