1985 MG METRO 6R4

Estimate: £180,000-£200,000 Some enthusiasts may consider it sacrilegious that an icon of the Group B rallying era, and later European rallycross, has covered just 175 miles in its 34-year life. But there’s a good reason, as this Metro 6R4 was acquired by Williams Grand

Prix Engineering in 1988 – the Formula 1 team’s co-founder Patrick Head and engineer

John Piper were consultants to Austin Rover Motor Sport during the 6R4’s development. It remained on display at Williams’s Didcot site until its auction in 2005. The current owner bought chassis 111 in

’15 and has since presided over a full mechanical recommission.
