Hi poweruser and welcome to the world of VW. Ryan has already given you the essence of the answer to your question but allow me to elaborate. Selling an antique or collector car is really a question of supply and demand. In your case a sedan ( I am assuming that it is not a convertible ) Super Beetle is in abundance as it was the last series built and was built in big numbers. Rare VW's are the convertibles ( about 330,000 of the 23 million built ) and pre-1968, 21 and 23 window vans. When cars are taken away from stock condition and appearance, a big part of the market is left behind. Collectors pay huge premiums for cars which are " time capsule " examples, original paint, no accidents, even original interiors and tires. While anyone can copy your custom work, if that is their taste in cars, nobody can create an untouched original. Super high quality restorations are possible using new old stock parts etc. and these too will command good prices. It is ever so easy to overbuild a car by "investing" thousands more than the car will ever be worth on the market. Just because you have spent that kind of money does not mean that the buyer will acknowledge your efforts by paying you more than they could pay for a better or rarer car. Go to Collector Car Trader.com and search using specific years, makes, models and geographic areas. Try looking just in California and you will see what others are asking for their cars. Now put yourself in the postion of someone with $10,000 burning a hole in their pocket. Do they buy your car or a Karmann-Ghia convertible ? You should learn rather quickly that the market is a ruthless place. Take your car to a VW meet and compare it around. That is also a good place to sell a car. People there are already interested and you may indeed score. Best of luck and if it doesn't sell, consider just enjoying your car. Unlike some makes, VW's are meant to drive. MY 72BUG
