I understand the burying the car in another, however I would still try to bury it in a cheaper car. Keep in mind you are prepared to pay $500 today to fix it, and that you probably could sell you stratus shell for another $500, so your really only looking to bury $2500. You buy something private party and then finance it on Retail, you can bury quite a bit of money. Although I'd be Very tempted to just buy a $500 beater/borrow a car so you don't go from being within a few payments of car loan free to re-starting a 4-5 year loan at the same payment, and just find yourself in the same boat in a year when the VW needs the front suspension gone through, or an Auto trans replaced, or the electrics let the smoke out, or whatever.
good luck with whatever you do.
