I'd buy at least one (right now). Preferably Silver Frost 98 EO. Although here's my .02...
Replicate each model respective to it's factory full size sibling! Considering there would be many more models than actual cars, make a "first run" of the model. If there were 2487 silver 98 CSVT's, then paint 2487 silver and call them 98 EO or E1. Changing only the paint and wheels would be the only real difference other than interior colors for 99 and 00. Supply a certificate donating this and then after that...make as many as it takes to turn the profit.
just my thoughts...I'd pay more $ for the model to have a matching certified #761 98 EO CSVT to go along with the real thing!!!
