Auction Car of the Week: 1987 DAM 4100 Metro 6R4

The MG Metro 6R4 is undoubtedly among the wildest cars in rallying history, one that hails from the sport’s most dangerous and bombastic era. This DAM 4100 Metro 6R4, on offer at the Iconic Auctioneers Race Retro sale on 20 February 2026, didn’t compete in the Group B category, but it tells a fascinating story of the 6R4’s life after the dust had settled. 

With an auction estimate of between £100,000 and £120,000, the DAM 4100 Metro 6R4 is widely recognised as one of the earliest and most significant DAM cars.

Commonly known by its registration, A14 LOO, this was the first prototype developed by David Appleby and Tony Pond from Clubman 6R4 chassis no.183. It remains closely tied to the pair’s short-lived but ambitious motorsport partnership.

Appleby’s background with Austin Rover Motorsport in the mid-1980s placed him at the heart of the 6R4 programme, working on the works rally cars of Tony Pond and Malcolm Wilson. When the 6R4’s international career drew to a close, Appleby and Pond acquired a batch of Clubman cars and set out to create a faster, more serviceable and more aerodynamically effective evolution. Although the partnership dissolved quickly, the idea persisted, and Appleby continued to refine what would become the DAM 4100.

The prototype here retains the original 6R4 wheelbase and features Kevlar bodywork with front and rear sections designed for quick removal, addressing one of Appleby’s key frustrations with the works racer. Power comes from a 2.5-litre development of the Cosworth DFV-derived V64V engine, fitted with a six-butterfly injection system and capable of producing around 275hp at 10,250rpm, plus 225lb ft of torque at 8,500rpm.

A twin-plate AP clutch, dog-engagement gearbox, drop gears and Salisbury differentials complete a transmission package intended for rapid cog-swaps and demanding rally stages.

Restored and ready to race

Despite being too late for Group B rallying, A14 LOO quickly proved its pace. After two early retirements, it won the 1995 Solent Stages, following that with outright victory on the Jersey 95. Despite only a small number of DAM 4100s ever being completed, the car accumulated a respectable list of results in period and earned a reputation for being both potent and thoughtfully engineered.

The Metro has benefited from extensive later work. In 2015, Appleby himself undertook a major overhaul, replacing the fuel tanks, pumps, filters, seats, fire extinguisher system and brake pads. He also fitted a custom stainless steel exhaust.

A full engine rebuild by V64V specialist Pete Goodman in 2018 cost over £18,000, and the car has subsequently been maintained by 6R4 expert Pete Slights. This includes recent work to its step-off unit and centre differential.

A piece of Metro 6R4 history

The 6R4 now carries a Motorsport UK Competition Car Passport and has appeared at various demonstration and enthusiast events.

With only a handful of true DAM 4100s in existence, A14 LOO is a significant piece of Metro 6R4 history. Ready for demonstration outings, sprints, hill climbs, rallycross and other non-FIA events, it offers a rare chance to own a car that championed the Metro 6R4 long after the demise of Group B.
