Don't do it until you can afford both cars. Unless you're pretty dedicated. Then go for it , a 60s VW can be a happy daily driver. It can be a bit of a heart break as well, but not many cars do that to you.
Issues, over priced, hidden rot, often poorly looked after, poor 'upgrades', bad paint jobs, cruddy chicken wire and filler 'welding', all the usual bullshit with an old car.
The very very best is a nearly as close to stock not too cut up solid original air-cooled type 1. Once you've a solid bug most other problems (engine, mechanics, etc.) are not that big a deal.
Say $4500 to $7,500 for a clean stock bug? Sounds reasonable.
Restored beetles, check up on the workshop, take someone who might spot bad work. I've found with even a very very well restored bug, they start rusting again quite quickly. More so than a normal original. Lower quality parts and inferior to factory paint job mean that spending $10,000 on a restoration, seven years later they look really sad again if they see a lot of road use. You rarely get your money back on the re-sale either. Hmmmm, best that you're idealistic to go through all this.
Right, you've bought one. Every 3,000 miles or 3 months you have to adjust the brake shoes and change the oil. They are high maintenance or they become a poor drive. The shoe brakes on a vintage beetle are not self adjusting. Aftermarket discs conversions are easy to get these days , I don't know if they are good quality or made of plastic, but I'd add it to your budget. The shoe brakes on beetles are awful.
The engines are really good (if they are not totally knackered out). If it's a fresh well looked after engine even the 1200, it should quite happily do its best for you. Like a well meaning lawn mower, it'll become your friend.
They are great at night with the round dash light, it's like you could be flying a bomber over Berlin, it really feels like it sometime as you yaw around a round-a-bout.
