Just a thought to start a discussion based on recent questions about classic racing.
So you want to go racing in one of the controlled formulas. TCR or TA2 spring to mind. But here lies the problem (as I see it), you can't build your own car out of what you have lying around from previous projects. In NZ we have many people who are more than capable of building one of these cars to specification without going overboard (or cheating) but it appears to me that one must buy the package from a recognised supplier.
My question is, is this detrimental to our sport. Whilst I am not totally against the idea, does the cost preclude some potential competitors who would like to try and compete on a shoestring budget?
