My favorite VWs in order:
1. Old Beetle
2. Mk5
3. Mk3
4. New Beetle
5. Mk2
6. Mk1
7. Mk4

I would have an old Beetle as my only car if it was practical, so thats why I have the Mk3. I use to have a Mk2 Jetta but it's boxy lines look rather old. I don't like the Mk4 chassis at all; I do like the 1.8T engine though.
