I prefer a four wheel drive vehicle, but here's something to think about. A two wheel drive with one of the best engines on the market strapped in. The thing is light, agile, and fast. It also has everything that a T-Maxx has (excepting the four wheel drive). To convert it to four wheel drive shouldn't be too hard if you feel the need...for four wheeling.
Just an assessment based on what I've read and seen online...haven't seen one in action.
