Howdy,
This one, at least for me as a "soon to be roadracer".
My overriding concern is running / consumable costs, not the costs of the car itself. I'm pretty well established, have a pretty good job, etc. And I'm _still_ worried about the $1k/weekend I'm figuring I'm going to be paying to run a "not at the front" effort.
If there were a way via the rules to control those costs, I'd say to go for it. But I'm not sure that's at all possible.
