If youd rather make payments on a newer reliable car do this. Take $300 a month and just keep replacing parts on the gp/gtp for 4 years (duration of the loan usually) by then you would have dumped $14,400 into the pontiac. At that point everything dam thing on the car would be brand new. And guess what, by the time you pay off the 4 year loan o n the new/newer car, youll be dumping money in it to fix it!

The main key is fix it before it brakes.

So see, its a never ending cycle. Dammed if you do, and dammed if you dont. The only "true" limit is rust and if you dont stop it. But with 14k being dumped, a new paint job with some rust bullet etc you would never have to worry about it. In the end your gonna always have a payment of something.
