I'll check my notes on the engine code when I get home from work today (close of business).

I'm really bad on the money part of it.

I prefer an auction format (BaT, or ebay) so that the market at the time can decide the value.

Are you a buyer or a seller? Im not really in the market for a new car, but that isn't all that far from me and that's a ride worth having. If its going below market to get rid of it quickly I might be interested.
