FOR SALE: 2007 COSWORTH CSR 260, 7,300 MILES, CA LEGAL AND SMOG EXEMPT, SB100, $53,000

[Darren]

THIS is not your typical Seven. The range-topper for over a decade, this specification commemorates 50 years of the Lotus/Caterham lineage (1957–2007).

Finished in Ballistic Orange with black accents, this British icon is powered by the bespoke dry-sump Cosworth 2.3L Ford engine producing 260 hp, breathing through roller-barrel throttle bodies and a Westermann carbon ram-air intake. Power is delivered through Caterham’s own close-ratio 6-speed manual gearbox housed in a lightweight aluminum casing, paired with a 3.62 limited-slip differential. At just 1,395 lbs, performance is immediate and intense.

The CSR 260 represents the most advanced evolution of the venerable Caterham platform, built around the upgraded CSR chassis—25% stiffer than standard—paired with fully independent double-wishbone rear suspension and pushrod inboard front suspension. The result is a Seven with markedly improved composure, grip, and stability, yet this upgraded version sacrifices none of the raw, analog driving experience.

Legally registered in California in 2014 as an SPCNS with a 1957 Lotus designation, the car is permanently smog-exempt and retains its SB100 certification plaque in the engine bay. The car has current DMV tags and a clean title.

Owned by the seller for 12 years, and with 7,300 miles on one of the last custom Cosworth crate engines to leave the line, the car presents in excellent condition following a mechanical refresh by Kampena Motors and a subsequent professional repaint in 2025.

In December 2015, with chassis mileage at 4,985, the seller replaced the original engine with a brand-new Cosworth CSR260 crate engine of the same specification, as the original motor had several technical issues, incomplete service history, and had spent its life at 6,800 ft above sea level. The chassis has 12,200 miles since new, while the replacement engine has 7,300 miles and runs beautifully.

The car has spent approximately two-thirds of its life canyon carving, blatting, and cruising, with the remaining third used on track.
