If you have full coverage insurance...or protection against theft, do this:
Take your car to a parking lot at night, take a baseball bat to it beat the shit out of it, crush the headlights, break or crack all windows, destroy the dash, dent everything, spray paint it etc.
The insurance company will total it, and give you a check. Put that towards a new Hyundai with a 100,000 mile warranty. You're driving a Cavy...so you obviously don't care about looks
.
If not that,i'd say just try and sell it/trade it on something more reliable. J-bodys are so problematic..
