Part of the allure of VTA is you can run your older TC and still be competitive. I run a TC4 that was my primary car 10 years ago, and I can still make the A most times. And there are plenty of people running TC3's. The LHS owner that runs the track races a TC3 that was given to him, and he hasn't maintained anything in the car. The shock oil is still in there from 15 years ago!
