I was pretty unlucky when I bought mine and I considered the torch or lake option, but because I expected the unexpected I engineered in a safety margin so if something did go wrong I had enough money to rectify it.
If you do get one though, don't panic if a warning light or two come on. From my limited experience and from trawling through NSXCB and Prime looking for a cure, it's very often a minor fault which has shut down two related systems.
For example; if the engine check light and the TCS light come on at the same time it might be an oxygen sensor, not a broken TCS unit! It's very rare that a car develops two problems at precisely the same time.
On the whole I am very happy with my NSX, I had a Boxster S before which is a very good car but the Honda feels special, outperforms the Porsche and sounds a whole lot better.
Cheers,
James.
