I don't see any money to be made there.

Even with the body fixed it's still an auto car with high miles, the price is still going to be low. Maybe a 5-6k car max, maybe.

The motor should be solid still, just broke in really for most LS engines. The 4L60e is still iffy, they aren't strong to begin with but the only thing it has going for it is a light weight car compared to being in a heavy truck platform.
