On the Honda website (Japan NSX) they offer ALOT more options than the Acura website "builder". Japan has more color options (green and a maroon/purple?), a GPS video screen ($5000), custom stitching, four wheel options and two console color options.
They didn't offer the camel or red color interior colors, though, just black with two various seat insert colors (yellow or blue).
Interesting options over there... don't know if the extra choices would increase sales... but Americans do like their options if they are offered.
Looking at the Acura NSX site, it seems there are only 25 cars available in the USA currently, and a few certified preowned cars.
On the Acura page, click on NSX at the top.
Now click on "Evolution of a revolution: story of NSX" (the picture in the lower right)
Let the macromedia page load.
Now click on "enthusiast" and then click on "NSX locator"
You have your choice of searching for new or certified pre-owned cars. One would think that this should be on the FIRST NSX page of the Acura website, but that would make too much sense and they may sell too many cars...don't want to make it too easy to buy a supercar!
Also the website has a nice "comparison" link where you can compare the stats of the NSX to Ferraris, Porsches and just about any other supercar out there...
