I own a T3 as well as a XXX-t mfe, Like LosiFromHell, we race together and have done much thinking on the differences between the two. 98 T3, the T3 is an awsome truck on and off the track, but with newr versions comeing out from both companie if you are in a sertain budjet range for racing I would suggest trying out the XXX-T mfe, its a great Truck like LosiFromHell said, but they are two totally different trucks. If you whant durability go with the T3 if you wahnt speed and a just plane awsome running truck, go with the XXX-T
