heehee Most of the ppl that I know and would let drive any vehicle of mine don't want to drive the 370Z. My Dad is 6'+ and has problems with his feet and legs so getting in/out is a PITA for him. My best friend is afraid he'll wreck it (kind of surprised me since he has owned RX-7s, Vettes, &c).
My daughter has driven it a few times with me in the passenger seat. Not because I felt I needed to be there; I wasn't going to walk home just so she could solo.
It's just a car and it's insured, so I wouldn't be too worried to let someone I consider to be a good driver take it for a spin.
I'm more concerned about ppl driving my POS pickup truck with the worn out steering and iffy brakes.
