I'll bite.
Lud is right - it depends on what you mean by "in the market". The most frequently-quoted market indicator is the Dow Jones Industrial Average, which consists of 30 blue-chip stocks. On September 6, 2000, it closed at 11,310.60. Right now, it is trading at 8,431.10. That's a loss of 25.4 percent.
If you had bought a clean used '95 NSX-T two years ago for $45K, it is worth maybe about $41K today. So it has dropped roughly 10 percent in value. Of course, there are operating expenses including overhead (insurance, licenses) that are not associated with the stock market investment.
Keep in mind that, on a percentage basis, cars tend to depreciate faster during their first few years. For example, a clean used '97 NSX-T bought two years ago, or a new '00 NSX-T bought two years ago, probably lost 20-30 percent of its value since then, assuming you didn't overpay when you bought it.
