bschwarz77 has already given you some good advice. Think of the entire thing as a cost - benefit analysis.
ON THE PLUS SIDE: Beetles are cool. Parts are still quite available and part costs are still very reasonable. Beetles are simple - a good amateur mechanic can do far more with one than what can be done on modern computerized look alike jelly bean cars. Beetles are part of an international network where help is available for whatever your problem may be. ON THE NEGATIVE SIDE Beetles are old technology. Newer cars are more reliable, faster, quieter, safer and within the same engine size are kinder to a tank of gas. They may be easier to work on but you will work on them more often. Their environmental impact would equal the operation of 3 or 4 modern cars. If you need heat and especially defrosting the cars have a deserved reputation for being " challenging " to put it mildly. The bodies are biodegradable for being prone to rust - depending greatly on the climate in which you live. SO: As a daily driver in my climate (Southern Ontario) - no way. As a summer toy or a show car or a drive down town for ice cream in the summer car - you bet! The Beetle is a great affordable restorable classic. It is instantly recognized by everyone at a car show and brings back memories for a whole lot of people. Be very concerned about rust. The rust you can see is bad; the rust you can't see is worse - floors, structural heater channels under the door sills, sub frame components. Don't worry at all about interiors - replacement stuff is widely available, easy to install and cheap to buy. Mechanical stuff is widely available and very reasonable. For what it can cost to replace the timing belt on a modern front wheel drive V-6 you can rebuild a bug's engine! Look at parts sources such as CIP1 and do some mental shopping. Go onto the Collector Car Trader.com website and enter the parameters for your search and you will see loads of bugs for your price range - again, think body and take someone with knowledge of the cars with you. The Super Beetle has a more bulbous front luggage cover ( hood ), a spare tire that stores flat in the front storage and coil springs over McPherson struts for the front end. Front fenders are a little bigger and the dashes are different after 1973. From this point on the decision is yours. There are loads of books out there which can help you. If you decide on a Beetle ( for whatever purpose ) welcome to the international club. Dan (MY72BUG) in Goderich, Ont.
I'd rather have a partial bottle in front of me than a partial frontal lobotomy.
