You can get a loan on a early 90's NSX, however you are going to be paying out the ass for it.

I was approved for a loan for one through NFCU for a certain amount. However, when it came to discuss the terms the first question they asked was how old the car is. Anything over 7 years old falls into a new category. Maximum loan term is 60 months, versus 72 months that is available for 7 years or newer. Plus your interest rate range goes from 5.5% - 10.5% to 9.5% - 15.5% .
