First upgrade you should do, is sell those POS VWs, and get your Jeep fixed up.
Haha just kidding! Heh, I have had my fair share of Veedubs myself. I was more of a classic VW guy myself. The nicest one I had was and old split-window I bought from an old school teacher in germany. I should have brought that back with me when I got out.
First upgrade? Tub and chassis. Definitely.
