Obviously as an owner of a 2010 ZR, my opinion probably has a bias, but my thoughts are -- you are either a "vert" person or you are not. As a fellow ZR owner put it a few weeks ago -- the top is simply a parking cover.
OBTW, I think you can still be interested in street performance and have a rag top -- I plan intake & exhaust upgrades for my vert.
THAT SAID, if I can only convince my wife to trade her Altima in for a NISMO Coupe, that'd be OK too!
