I guess I need to be realistic about what I can afford and what I think I can afford.
I had a blast with my Cobra but after watching a few cars bounce off the walls at Mosport this year I started re-thinking how smart it is to take a 25K dollar car out on the track that I'm still making payments on. Granted I wasn't driving the car at 10/10ths, I was out having fun chasing around people that I knew. If something were to happen, I'd be watching from the sidelines for awhile.
So I spent the last few months deciding if I should just stick to Auto X at Devens and stop doing HPDE days or if I should just face up to the fact that I love this and just get a dedicated car and keep going.
I decided to sell the Cobra and now I'm trying to figure out what to buy. I have had the opportunity to Auto X a whole slew of cars over the last few months which has been a lot of fun.
E36 M3, E36 325i, MCoupe, SVT Focus, Miata, about 10 Mustang/Cobras, C5 Z06, C6 Z06, and I can't remember what else. I liked the E36 M3 the best, what a fun balanced car.
The prices for a setup car are more than I want to spend and then I started reading about SCCA Wheel to Wheel Enduro races and it sounds like a ton of fun.
So without any of my Mustang friends looking I wandered over to the Spec Miata site and started reading.

Hmm turn key cars for 8-10K ready to race? Tires and brakes last more than a weekend?
I can say that I understand why there are so many people driving these cars now. Its really the only thing that makes sense if you want to try and run a car on a "budget". I think it would be fun to do some wheel to wheel racing, parts seem cheap to replace and the car doesn't seem to need constant attention other than the normal wear items.
Then again, its not the fastest thing in the world. I'd be worried that I would get bored to death... But at this point Its better to be running in a slow car than in nothing at all. Hopefully the competitiveness is where the real fun is.
So as I'm "typing" out loud here. I think I need to decide, do I want to do HPDE and Time Trialing only or do I want to start looking into also doing some Enduro W2W racing? If its the later, I think Spec Miata is the only choice. If I wanted to just run with COM and play around in the time trials I could go get an E36 M3 and throw a bar in it and have at it.
At least I have all winter to think about it... But back the original questions, I was curious how you prove ownership. I figured I could do some laps around the neighborhood, I mean what other choices are there...
