They are two totally different cars. You can't really compare beside the fact that they're both two great cars. Elises/Exiges are purpose built machines that's awesome on the track where they're suppose to be. I think Lotus should void the warranty for any Elise/Exige that has never been to the track
. On the other hand you can take the NSX cross country and you don't have to go to the doctor's office afterward for back pain. They are both reliable but the NSX is better built and stuff don't fall apart as easy as the Lotus.
