Floor pan change is sadly a real thing....I've never done it, and don't feel up to it, which is why I got away from those cars, get one that does not need it, from a dry state. Always look under the battery, that is where the rot begins....pro-tip, I put the battery in a polyurethane box designed for boats, to keep the acid at bay, and to avoid the springs in the rear seat from sagging onto the terminals and causing a short/fire if someone sits back there, again, ask me how I know. :/ Please remember, and this is hard to explain to a younger person, (no offence intended at all) these are NOT modern vehicles, by a long shot, be very aware of what this means pre-purchase. Another pro-tip, the stock brakes, drums at all 4 corners, have not one, but two star wheel adjusters for the pads, when replacing brakes, get the hardware kit, just do it, and adjust both star wheels the same # of turns, I can't tell you how many I took apart grinding that had 1/3 of the shoes down to nothing and the drums ruined because people did not know this. I always as a kid wanted to be able to get the tooling to produce bug floor pans in stainless steel, to kick rusts ass. :) I have owned close to 100 cars in my life, and there are only a few I really miss, my 71 super beetle convert tops that list, but it was a mobile oil slick, had shoddy body work, looked good at 5 yards though, and a 1k top, glass rear window. Sigh...I LOVED that car. Air cooled VW are like mopeds, they can ruin your life, in a fun, though expensive way, be prepared young skywalker! ;) If you are clueless about bodywork run from Giah's, the fender seams were leaded from the factory, a serious skill that most body shops no longer practice. The convert Ghia, is a very sexy car, but be prepared to lay out huge money for a solid one, more than it will ever be worth. I don't mean to dissuade you from buying one, but be very aware of what you are getting yourself into. They are summer cars only.
