Not planning to rust out the datsun with road salt. Besides, I just sold a cheap 4wd away less than a month ago. 4wd is boring if there isn't lots of power, be it winter or summer. Some Evo or STI might be nice, but those aren't exactly cheap cars to bash around.
I used to know a guy with one, he loved it but I think he got kinda bored after a while and the space isn't very good, though you will be surprised at just how much you can fit in a Polo. I'd love to have one, I think it's 120bhp form the 1.6 which in such a small car would for sure be pleanty of fun. Though the guy I knew sold it and got a Leon Cupra, Good swap imo, maybe you should look into the 1.8 turbo Golfs or Audi A3's? I think the prices may be around the same or less depending how many miles at has etc.
