dang nice list of cars. I'm trying to decied between an nsx or and rx7 for my next toy. Sold my s2000 about a year ago and miss it everyday.RX7 over an NSX, I had a NSX-R GT, was an amazing car but also extremely expensive to maintain, and if you don't have a specialist work on it for things like clutch changes they can easilly damage the chassis and subframe.
I'd recommend an RX7-FD3S RZ.
Or if you really do want an NSX over the rx7, try and find a used GT2
Or like my friends! check it out.
