Last week, after six weeks in the shop, I had my NSX returned after repair. The collision conditions were classic...worn rear tires, wet pavement (just barely), but the speed was less than 40 mph on a straight section of road. When I lifted the throttle to avoid running into the back of a vehicle that pulled from the side street into the far lane, the rear end broke loose, I hit a concrete barrier wall (left front), and spun 360.
Result: $15 damage (replaced left frame-rail and misc). I'm happy with the work but I now have a leak somewhere up front and will be taking the car back. The master cyl reservoir is also low (I always keep it topped off)
Recommendation: Keep adequate tread on your tires, keep the car insured, watch for idiot drivers, become familiar with the performance of the NSX (get your track time in under both wet/dry conditions) so you can experience the polar spin thing. It's surprisingly quick and difficult to recover from.
I've had this vehicle for over 15 years and don't plan on selling it. The look, low maint cost, and performance is what I enjoy. I looked at other vehicles (viper, corvette, bmw. lotus, porsche) before purchasing the NSX. The cost of these cars was way out of line when getting a plastic interior, uncomfortable seating, extreme maint costs,and non-classic looks.
I'll be keeping the NSX
