Looking at the 94 brochure in literature section, there were 3 white colors for 94 SC's, Vibrant White, Opal Frost and White Opalescent. All were available with the Portofino Blue interior.
The 95 brochure lists 2 white's for 95 SC's, White Opalescent & Vibrant White both available with Portofino Blue interior.
Considering the different color options for exterior and then the choices of interior colors your probably look at about 40 total made in the same color combos w/ the 5spd option.
I mean for each interior option you either had full leather or half in half also so it narrows down a lot.
