yea, i got my xterra used, well my parents got it, and they didn't really check for it being 4wd or 2wd, and they got one that was 2wd, its fine for on-road, except when it snows, i'm not an offroader, mainly because i didn't think it would be good in it, and if i were to get stuck, none of my friends have SUV's. I regret it being 2wd at times, especially in the winter, there is absolutely nowhere i can go with this in the snow, its horrible. I was wondering if you guys recommend me trading it in for a 4wd one, or tips on making it good in the snow as is.
