well.. unfortunately mods make it decrease in value... but there's always some jackass who doesn' tknow what he's doing and thinks a shiny coat of paint, body kit, and rims add 50 horsepower. so if you wanna sell it quickly... under $3000, but if time isn't an issue, start at $8000 =D at least you could make a profit.. like i said, tehre's always some dumbass out there =D
