I still gotta say, the xx4s are just easy to drive fast. Jumps great and sweet in the bumps.
Didn't say you can't break em but throw it down and it NEVER handles poorly.
I was drivin a xxx4 and really, really liked it and it was even on a semi bumpy track but when I put my xx4 back down just for fun it was way easier to drive fast.
Like a 2 wheel drive with 4 wheel drive turning. I'm stickin with it and parts are available again/still.
If I drive smooth and don't crash hard it is the funnest car I've ever owned, that's over 20 years off and on. (more off but nonetheless 20 years)
