I would need this Vert option just to drive a stock nsx! i got in new NSX at the dealer a few years back & i had to duck down when sitting in the seat, at 6'3 the roof inside was even with my chin, i needed to lose about 5 inches of height just to sit in her,. i hopped out right away, grossed out. I remember now being pretty ********** at honda/acura. making a car for 5'5" people? at least make a seat lowering option from the factory if you plan to sell a car in the USA. that was my take anyway.
