I'll spin off another thread.
Why does an NB car cost 15k more than an NA? The prep is identical. The cages are identical. Suspension package identical. Performance very nearly identical.
I'm genuinely interested in what the builders have to say about this. In my opinion this is one of the biggest reasons we can't get new people into road racing and especially SM. There is a perception that buying into an NA is a big risk, but NB pricing is kind of ridiculous when you put it into cost vs. performance comparison.
If it is market forces driving this up it might be time to really examine where this pricing is coming from, because it hurts the future of SM to keep NBs expensive.
