If you havent purchased on yet.....Run a magnet over the entire body, telltale of bondo is it's not magentic. Also, pull the back seat out and look at the floor pan under the batteries, VW's are notorious for corrosion under them.
Also, with the car being so old try carfax or carfacts to see if there is anything on the car ever having been in awreck.
If either on has ever been in a wreck the front end will have tell tale signs in the trunk space.
You may be lucky in that both have been restored or repaired, but have it checked out by a VW tech to make sure, it wont cost more than 15 or 30.
should you need parts in the future HOTVW is still being put out by paisano publishing, most places dont carry it put it is online and barnes and noble does carry it.
good luck, with either one....my very first was a awhite 1972 bug.......no super's ever. like everyone else said they are more exspensive to buy for and do have their own set of prob's.
