The History of Andy's Marcos GT
This Marcos GT gullwing coupe was a racecar from new! It was originally owned and
raced by Stephen Minoprio in England. Mr Minoprio was the 1962 Autosport Championship
winner in his class with this car, and he continued to race it for many years. The
car's international and national (U.K.) race history includes races at Goodwood,
Silverstone, Brands Hatch, etc.
Colonel Andy Seward purchased the car in 1994 while stationed with the U.S. Army in England. Andy raced the car in the U.K. and Europe from 1994 through 1997, but his situation obliged him to sell it. The next purchaser relocated to car to Japan, but eventually Andy tracked down the car and arranged to repurchase it.
The restoration shown here was completed in February 2009. General repair and restoration work was completed by the owner. Race prep and final completion of the restoration was by Dave Handy at Sasco Sports in Alton Virginia. The new paint is a Jaguar color called "Cotswold Blue" (circa 1959-1964) and it was applied by Brian Tocke of Fredericksburg Virginia.
