2021 Caterham Seven 420R Race Car

A superb opportunity to acquire a proven front-running Caterham Seven 420R race car, built in 2021 and campaigned in the official Caterham Motorsport Championship.

Having never completed a full season due to the owner’s business commitments, this car has enjoyed considerably less use than many of its contemporaries, while still proving its pace whenever it has taken to the circuit.

Its most recent outing came at Silverstone in 2025, where it delivered an exceptional performance with three podium finishes across the race weekend, consistently running at the front of one of the UK’s most competitive one-make championships.

Built to current Caterham Seven Championship UK (CSUK) regulations, the car benefits from a brand-new engine fitted at the start of the 2025 season. The engine has completed just five race weekends, offering exceptionally low mileage and an excellent platform for competitive racing.

The car is supplied with an HD VBOX data logging system with brake and throttle trace, allowing detailed driver analysis and performance coaching. It also comes complete with two sets of spare wheels, making it an ideal package for anyone looking to go racing immediately.

As one of the UK’s leading Caterham Motorsport teams, Williams Motorsport can continue to prepare, maintain and run this car for its new owner through our comprehensive arrive-and-drive programme. From transportation and race preparation to trackside engineering, driver coaching and ongoing maintenance, we can provide a complete motorsport solution.

Fast, proven and professionally maintained, this Caterham 420R represents an outstanding opportunity to join the front of the Caterham Seven Championship UK grid with a race-winning package.

This is a competitive and well-maintained car, ideal for someone looking to experience and compete at the top level of Caterham racing.
