Looks pretty solid - lifelong black plate California car. Nothing special as far as powertrain goes, but these days, I'd be happy getting the old 307 running and driving and enjoy it as-is.
I'll bet you could CLR that paint back into shape, at least so that it looked like a single white color.
Not a bad car/truck for $6k.
