What is it???
Just about the first question any owner gets asked.
The Caterham 21 was intended as a practical version of the ever popular Seven,

With the development of the 21, Caterham were able to resurrect classic British performance car appeal, with the lightweight performance and handling of modern Seven Racing.
Originally intended as a low-production run car of no more than 200 a year, only just under 50 were ever made and production has now ceased.
The Caterham 21 Owners website and List aims to help us stay in touch, keep the cars on the road and provides somewhere for propective owners and enthusiasts to find out more.
Recently, we've organised for a Caterham 21 to be seen on a stand at the ever popular MPH show at Earl's Court, alongside a classic Lotus 7 Series 2, a JPE 7, an SV and a Graduates racing car. The diary for next year includes;
- International Historic Motorsport Show
- Stoneleigh Kit Car Show
- Various 50th anniversary of the Lotus/Caterham 7 events
- Annual Curborough gathering
- Assorted trackdays (more to follow)
