Buying My First Muscle Car 1973 Duster 340 Interior Pic

Hmmmm. To me that's more than a little rust. It's clearly in the left rocker and where it meets the floor pan there. Spare tire wheel doesn't look very promising either. I don't know enough to comment how that affects the price of a factory 340 car. Negatively obviously. Seeing that now, to me, this car will require some skilled inspection by someone that knows these cars well.
