I LOVE the scale appeal of USGT and VTA, even though I don't run either. I sold an SC truck so that I could pay for a TC4 Team kit, already assembled, just so I can treat myself to an awesome-looking body and wheels once in a while.
I don't have the money to race regularly, or at all, but if I do get the chance, I know I'll be smiling ear to ear as I watch all these scale sports cars zooming around the track.
I hope these classes only continue to expand in participation, without the pressure of allowing unlimited motors, wheels, tires, and most of all, ridiculously out-of-scale bodies (TC as far as I am concerned)
