Good luck getting anywhere near that asking price. As a general rule no one pays the cost of mods when buying used - they are a loss on your end. Buying a car that modded - regardless of how well the work was done - is a big risk. Those kinds of mods already are reducing the lifespan of the car (though it will be a heck of a ride for a while, I'm sure). As Busyallthetime said - getting back the sticker price would be a good deal for you. You might be better off taking off the parts and selling them separately (assuming you still have the OEM stuff).
