Re: so terribly sad...i HAVE to sell...
Sorry to hear about the big 'D.' As others have stated, all things shall pass.
What you might want to do with the car is take it back to bone stock (essentially) and sell all of the add-ons separately. When it comes to used cars, it seems that many folks are not concerned with the mods and/or would rather modify to their own taste.
Either way, good luck.
