I dunno, dont wanna spend too much, maybe 2.5-3K? I like to spend most of my money on my main hobby (the stang) since its not selling I may keep it, I cant make up my mind hehe

 

I think a scrambler 500 is right for you. You can find them cheap. They are a 500cc(38-40hp) auto 4x4. Its a nice mix of utility and sport they are pretty fast but yet can go through just about anything in 4wd. I loved mine...

If you would like more info on the scrambler head on over to the polaris forum.

I see you have a mustang, i do too, it was my first hobby as well...

 

It really comes down to what used quads are available in your area. The best quad for the best deal.
You should be able to find something within your price range.
