s2000 would be about 5k cheaper. Personally i would take the z and not just because im in the nissan family but because of the car itself. I sat in both and the 2000 is very very small. Where as the z has a little more roomy of a feel. Im sure the 2000 is more reliable, and the convertible would be fun. I am considering the same choices myself for my next ride. The z also has nasty blind spots. I would go test drive eacha nd compare. Only way to do it.
