OK. This is the car that was designed and developed by Lotus in 1989-91.
I'm struggling to recall the exact proposed name of the Bulgari car that was brain child/dream of Gianni Bulgari and got built to prototyoe-only stage in 1990 (called GB1 from memory, with a nice winged GB badge on the front hood/bonnet), and the project wa briefly known as 'Enigma.'
The car had an unusual patented seating system (patent number B60N1/00) with three sets in the front in a V-formation and a central steering wheel, plus two conventional folding seats at the rear. Is this enough, or do you still need more?
