LS-1 V8 NC Miata, North Carolina

I raced spec miatas. Interested in this car for street use and maybe a few tracks as instructor. No hardtop and won’t fit over roll bar according to seller (seller seems very straightforward), no brake upgrade.
Curious what people think this car will go for?

With 2 days left in the bidding & it's at $18,500 it'll probably get much closer to $30K.

Thanks, I saw a white one this year on BAT that brought $31.9 with hardtop and brake upgrade but otherwise very similar.
I bet you are close!

Actually sold for $31,500 according to BAT website

Bring-A-Trailer now posts it sold for $31,500
