Hey man, hope it’s going for a good reason. It all depends on how much you value your time. Also if you kept your stock parts. Do you have a place to store them until the parts sell?
If you spent 30k you’ll be lucky to get 10k back. Thats after tons of headaches, flakes, low ballers, no showers, etc.
If it were me, and I didn’t need the money, I would take a few of the higher cost, easier to sell items off, drop the vehicle off at a dealer. Or sell private party for more $. But it might take a while to sell, and you have to deal with people.
