Ouch! My eyes are burning!! The main rust is in the floorboards. There all Fred Flintstoned. The body is just as straight on the other side and the only body rust is either easily repairable or happens to be located in the area where fiberglass fenders and front end would take care of it.
Good looking little Austin! If the price was right, I'd find it hard to pass up also! I see them occasionally, but mostly either already hot-rodded, or just not worth fixing up. Floors are no big deal, as they're easy to replace. That grille will be expensive, and tougher to find.
