Driven a Cat, infact their built not so far from where I am now.

Couple of things.
How tall are you?
How fat are you?

If you're tall then you might find you cant put the roof on and drive it easily. Obvious problem if you are fat Handle great, Doughnut easily and controllable (first donuts I ever did were in it!) Not that cheap mind for what you get.

If you cant fit in one but still want something thats bike engined, RWD, and cheap for a track tool/ fast road then consider this.
