I just looked on MSNAutos and got this for the MSRP:
1991: $62,000
1992: $65,000
1993: $69,500
1994: $75,000
1995: $81,000
1996: $79,500 (coupe) $83,500 (T)
1997: $84,000 (coupe) $88,000 (T)
1998: $84,000 (coupe) $88,000 (T)
1999: $84,000 (coupe) $88,000 (T)
2000: $84,000 (coupe) $88,000 (T)
2001: $84,100 (coupe) $88,100 (T)
2002: $89,000
2003: $89,000
2004: $89,000
2005: $89,000
Not saying it is completely accurate but it is probably close.
In 2005, Acura of Bellevue (in Washington) had a red 2005 for $69,999. I went to the dealer to check out the car. I knew it was a steal. I told my friend to buy it, but he jumped on an Audi. Now it's been a year and half the 2005 NSX has not gone down much in price while my friend's Audi is taking a serious depreciation.

Maybe the answer is easier than you think. Consider that you can get a GT3 in low 70's. Way more car for the money.
Also, fluctuations in currency exchange rates.Inflation my man.
