Absolutely nothing.
Comfort and ride are excellent.
Very cheap to run, although tires only last approximately 5,000 miles.
Pretty economical on fuel.
Reliability par excellence.
Good boot space, but little inside cabin.
Compact spare tire saves space.
I have been driving NSX's for 13 years and would never change.
8000 miles in 6 years?
Must be your fun car for week-ends and special occasions.
