http://ebay.com is the best place, thousands of sellers, lots of models and diecast..Jouef makes a nice first year 94 GT in 1/18 diecast that would be the same, comes in different colors... I doubt you'll find a 95, but the 94's are the same...here's some on Ebay...I doubt you will find a white one, so you may have to paint it..

and remember, new ones are being listed everyday..so do a search and ebay will notify you of the new ones every day...
Let them do the searching for you..
