Well, here's another possibility:

I haven't purchased a full stock exhaust for the car (I threw the one that was on it away after installing the turbo-back because I had to cut it off) yet (since I don't know if it will sell stock or modded) and I'd like to keep the seats that are in the car. So, if you wanted the car without the stock exhaust (in other words, you replace the exhaust, not me) and without a set of seats (this would be a simple task for me to replace, but the time it would take to pull the seats (2x) and install the seats is worth something to me) I'd do $1500.

What do you say?
