well personally its down to what ya use the car for and then try a mates car with the conversion
i went out in max's car last week and he has the same spec as me except for i got a t34 and hes has a hybrid T3, hes car is sooooo much more fun to drive so tbhj i think im going back to a T3
so test a few peoples cars and see what ya like for the use ya give it
