when this car's body finally does become undriveable im probably going to buy a regal GS, a super clean southern car. if i got it oiled every year perhaps it wouldnt rust much. i use a process called krown, but the grand prix had already been ravaged by winter salt when i bought it. i bought it fairly cheap and its been a good car but they seem to rot out. i have also heard that the regal doesnt rot as bad. i very much like both the L36 and L67 engines, at 160K the engine runs extremely well. it's everything else that starts to fall apart. if it werent for the salt i could drive this thing for another 100K easily. man i hate that stuff
