Nah, just the dirt. The fucking Ozark Mountains kick up so much dust through the valleys. But as far as rust and shit, not really.
My first car was a '75 Pontiac LeMans SC w/ a 400ci and R.A. IV heads. It was bad fast, and will be dearly missed. A friend wrecked it when he tested out my new exhaust for me. You gotta learn the hard way, sometimes. The front tires came off the ground and he was steady steering left and right thinking the linkage broke. When the tires finally hit the ground it curbed left and into a pole. Destroyed the front end.
The day I bought the LeMans, I had $20 in my pocket. I put $15 in from empty, topped it off at full, and bought McDonald's with the left over $5. LOL
I've been a Pontiac kid my whole life, and I see nothing changing. LOL
And the whole yellow thing. Yeah, I feel you. All my friends were doubtful of it's manliness until they rode around in it through heavy traffic.
As soon as I go back to that town where the '79 is for sale, I'll shoot you a pic. It may be worht your while if you have the money.
