Looking at buying a 1968 Dart with 440
I'll bet that was originally a vinyl top car. They all rusted at the seam because the factory just did a quick smear with plastic filler. Then when the cheezy red paint job was applied, they just skimmed over the rust. Now, years later the ugly is showing through.
Repainted gold, with wide steel wheel and dog dishes, this car will be sharp. Resist the temptation to add GTS badges to keep it a sleeper.
