The early 80s mexican bugs were very good. That looks like an excellent example. I had a velvet red one. The build quality was on par with the last german ones. The only weakness, IMHO, is the body was painted on the pan, and the underside of the pan is usually just primer. When they arrived in Germany, VW coated the whole underside in thick hard underseal. As it ages it goes brittle and cracks. Water gets underneath it and gets trapped against the metal causing localised rot, which usually doesn't spread far. If I'd kept mine I would have chipped off all the old underseal and derusted any surface rust, and used some wax based underseal instead. As long as its looked after, they last and drive very well.
