The more you get behind the wheel, the more hooked you will be. I auto-X'd my TT for about 5 seasons and 3 of them were sponsored by a local dealership.
Building either of those would be awesome. I think my next project is going to be a Shelby Cobra (replica). Leaning towards Superformance. I have been close to several and really like the fit/finish.
My wife just got me a NASCAR Experience package at the Richmond Raceway. She rocks! Not a huge circle track fan but it should be a blast. She knows I will drive anything that makes noise and goes fast. I plan on getting the brakes replace on the TT and taking it to VIR. A lot of my friends go pretty regular.
Here is what I did this morning. I finished the front spacers...
