A 1984 Audi Quattro once owned by 1992 Formula 1 World Champion Nigel Mansell is up for sale - with an estimate of £30,000-40,000.
H&H will offer it at its Imperial World Museum, Duxford, Cambridgeshire, auction on 20 April.
Apparently, Mansell needed a fast, agile car for the tight and twisting roads of the Isle of Man, his then adopted home. Damian Jones, sales manager of H&H Classics says: 'The Audi's turn of speed and sure-footed handling made it a popular choice with drivers, but this particular example would have been a challenge beyoned that of most wheelmen.'
Driving for Team Lotus at the time, the future F1 and Indycar World Series Champion sold the coupe following his move to Williams in 1985.
Treated to an extensive restoration since entering the current ownership in November 2011, the Quattro's rejuvenation was a labour of love for the vendor. Thoroughly overhauled, its original 2144cc five-sylinder 10-valve powerplant benefited from a reground crankshaft, new exhaust manifold, re-cred radiator, fresh clutch and a stainless steel exhaust system.
Julian Roup, head of communications for H&H adds: 'In th same way that estate agents speak of position as the ley thing in selling property and adding value, so auction houses selling classic cars will tell you that it's all about provenance. With Nigel Mansell's Audi we should see this in play.'
