Powertrain warranty is 60K but they'll void it if there's any significant mods. Be sure to test drive the car and get a feel for how the car was treated (especially the transmission). I'd say 13K for a relatively low mileage 02/03 would be reasonable, most higher mileage ones are going for 12-ish.

Even with rims and an exhaust I never get a second look from cops. I dont know how many times I've almost shit myself from flying past a cop doing 25 over and he just keeps on rolling.
