That step side sounds about like they are selling it at cost, I could easily see spending that much just on the work they have done. Look the body work over real good, maybe even take it to a body shop and see if they can find any trouble spots like poor repair practices, that would be my first concern. Being from Texas has it's downside too, they don't really rust, but they do sand blast, and when you bring them back up here, then they REALLY rust, so have a look at that too.
