I have an 08 700 xtx. its efi which is great. Ive had it sooo loaded with birch blocks that it wanted to flip over backwards climbing a steep hill, i just rolled back down, put one of the blocks in the passenger seat and drove up the hill. it was awesome. I also dragged my sisters ford ranger about 300 feet thru mud up to a foot deep without any problems at all. The prowler is very versatile. can be fun and fast, but is also a great workhorse.
