I started with the rally version of the tt02. What it is consists of the Lancia Delta Integrale Body, it allows you to flip the hubs for increased right height, 19t pinion and rally block tires.

Getting this allows you to easily convert to on road later if you prefer but getting the Buggy version would be better if you had an "offroad" track. I took my rally car on an off road track and it loved nose diving off jumps (going off the gas, and then full punch helped jumping - nearly landed a triple!) and it stayed undamaged for possibly 10-15cartwheels amazingly..
