I suggest a modified B4.1 over B44.1 .

More maintenance, more complex to drive well, you're going to break more parts learning to drive it, and a lot of places don't carry many parts for it unless It's real popular in your area (seems like It's not at most).

This has been my experience with the car the past few months. A mod 2wd is going to be a pretty big upgrade from a stock truck.
