White interior versions are quite rare, five production colors are known.
The orange enamel is a protoype ,seen in the 1969 catalogs.

Fuel tanks were developed for all four of the open wheel cars in an attempt to adapt the cars for use with
the "superchargers" however, they were never released to the public.

This Lotus was made as a giveaway for a banquet hosted by Mattel at the 1969 NY Toy Fair.
Each place setting had a chromed car with the silverware. This is the only known Lotus.
