2016 Caterham Seven 420R

The Caterham Seven 420R sits near the top of the Seven range, pairing a Rotrex supercharged 2.0-litre Ford Duratec four-cylinder — good for 210 bhp — with a kerb weight of around 490 kg on the S3 chassis. That platform, Caterham's most structurally refined iteration of the Seven, brought a wider cockpit and improved rigidity without blunting the car's raw, unfiltered character. The 420R specification adds the full 'R' pack: integrated roll hoop, harnesses and aerodynamic components that make it a credible circuit tool as well as an engaging road car.

This 2016 example has covered just 2,136 miles — a remarkable figure for a ten-year-old car. It has clearly been used sparingly, whether as a weekend toy or a garage piece, and the S3 chassis ensures the fundamentals remain as sharp as when it left the factory. With 0–60 arriving in around 3.8 seconds and a top speed of approximately 136 mph, the performance case is straightforward.

At £30,000, this represents strong value for a nearly unused 420R — a car that in standard ownership would typically see track days and spirited road miles accumulate quickly. The low mileage here is the defining characteristic of this particular listing.
