This is the definitive story on the production and concept of the Lotus Carlton written by Ian Adcock. The book was leather bound and a limited run (like the cars!!). The book was launched at a price of £120 and flopped, copies could be had at the time for as little as £30. The books covers the concept idea of a Lotus Senator right through to production and there is a chapter on the Pininfarina Chronos too.
Estimated value: Up to £120 depending on condition
