Out of curiosity I wrote to Caterham to find out the original build info for my car. Here is the response:
Sold by Caterham Cars Ltd in 1989 as a starter kit, this was supplied as a black De Dion Caterham Super Seven 1700 crossflow, with 5-speed gearbox, flared wings and Supersprint bonnet.
Spec included weather equipment, flared wings, 11" Motolita steering wheel, 14" KN Ford wheels, heater and roll-over bar.
Since that time the car has turned green, dopped a gear (now has a 4 speed???),been converted to dry sump and made its way around the globe from the UK to Japan and now Canada while travelling 30,000 road miles.
