Started the kit car revolution. Colin Chapman's purest expression of lightweight performance. Sold as a kit to avoid purchase tax, the Seven became the template for every lightweight trackday car. Caterham bought the rights in 1973 and still builds it today, virtually unchanged.
History
Colin Chapman designed the Seven as the simplest, lightest, and cheapest sports car he could conceive. A space-frame chassis made from steel tubes, aluminum body panels, and the buyer's choice of Ford engines kept costs minimal.
Sold as a kit to avoid UK purchase tax, the Seven required buyers to assemble their own car. This wasn't a compromise but an advantage: buyers learned every bolt and cable of their car, making maintenance straightforward.
At 460 kg with the Lotus Twin Cam engine producing 125 PS, the Seven offered a power-to-weight ratio that embarrassed cars costing ten times as much. The experience was visceral: no roof, no doors, no weather protection, and acceleration that pushed you sideways in the seat.
When Chapman moved Lotus upmarket with the Europa and Elite, he sold the Seven's manufacturing rights to Caterham Cars in 1973. Caterham has continued producing the Seven with minimal changes, making it the longest-running sports car design in production.
Original Lotus Sevens command GBP 30,000 to GBP 80,000. New Caterham Sevens start at approximately GBP 25,000.
