For the right price, I'd go NX over SE-R. I've just never actually owned a SE-R, but driving them brand new and used several years later, they drove like no other sport compact. I've owned so many it would dizzy most humans. I did own a NX for a short while until I discovered all the paint work and it had that stumble during normal acceleration between say 1800-3000 rpms. The had figured it out several years back on the forums. That NX handled unbelievably, guessing the SE-R's are about the same with v/Z-rated tires like what came on the NX's.
