The v6's are fun actually. I had a 75 shot on mine. The 3.8's stock dont hold the best amount of power at all though and the 7.5 rear ends will bust up with a sticky tire and a nice good launch....hahaha
Other than that...the turbo 6 is real neat and would prolly be a blast to drive if you took care of the little stuff that could break!
Along with others, i think its cool as well!
