In keeping with Britain’s position as the European home of the open-top (UK residents buy more than Italy, Spain and France together), sales of used Caterham Sevens are up nearly 25 percent on last year.

The introduction of the critically acclaimed new Ford Sigma engine range this year – entry level 125 bhp, 150 bhp and the track day R400 weapon – have boosted nostalgic interest in the outgoing K Series powered models like the Superlight R300.

“Interest in the new Ford Sigma engines and the R400 have certainly helped us freshen stock as owners buy new again,” says Andy Noble of Caterham Cars. “Customers have a greater choice at this time of year as new car orders for spring delivery start coming through the door.”

Caterham has sold over 12,000 examples of Colin Chapman’s legendary light weight sports car since 1973, when it officially took over manufacturing and distribution rights. Many are still around today with some owners well into their twentieth year of ownership.
