That is true, provided it is a model that people have an interest for in 25yrs because it was a limited edition model such as an R32 GTR V-Spec II, R32 GTR N1, Aussie delivered R32 GTR or even an R34 GTR NUR but at the end of the day you have a mint condition R33 GTS-T.
Sell it, buy a clean R33 GTR and drive the thing instead of looking at it!
