Got the urge to VW

[wanabee]

First of all I want to say this is an awsome Forum!
I have been into hot-rodding Detroit Iron and currently have an '85 Mustang GT that I have grown tired of mostly due to the the smog laws I am blessed with here in California.
I want to try a VW and I have a preference for an old Beetle. What should I be aware of as far as best years and potential problems. I don't want to get ripped off.
Any advice will be welcomed.
