I got my 4x4 when I was 19 and its absolutely lovely. to those of you who think 4x4 is easier to drive fast, your so wrong you don't even know it.
efficient driving with a 4x4 (track action here, not streetracing) is very difficult to learn, but when you got the hang of it - nothing can keep up

If you never have owned anything with big power and RWD and turbo - get a 4x4 to start with. they got a better engine too

P.S: when a 4x4 get sideways and snaps over - your chances are waaaay better in a 2wd. belive me! I got it sideways in around 100 mph and when the counter came I didn't even have a chance to start turning the wheel from lock before I was going backwards... Kept it on the track though
