Wrangler: impractical, fun to drive in nice weather, girls seem to like them.
Jetta: practical, #1 car preferred by homosexuals in the country (actually saw that in an article so I'm not making it up.
If I were, say, still in high school or something I would probably go with the Wrangler (lift kit, bigger tires, snorkel, bars, etc). If it were me now (23 and working) I would choose the Jetta... and no I am not a homosexual. But I wouldn't mind having a Wrangler as a fun spare car.
