Bob Usher-Sparks' Heavily Modified GTD40 Race Spec for Sale
Bob Usher-Sparks' heavily modified GTD40 is for sale. Having commissioned it's build and race development by Neil Bainbridge in the early nineties and raced her in the UK and Europe I sold this car in 1996 but bought her back a couple of years ago from her time spent in shows and track days. Refreshed during 2005 she is ready to race, sprint or hillclimb. Also UK road-registered K4OGT.
GT40 MkI Re-Creation - GTD Chassis heavily modified and developed principally for UK and European circuit racing.
UK Road-Registered 1993 Registered Number: K4 OGT. New MOT Certificate.
Available to view in Caterham, Surrey, UK (Junction 6 M25, about 20 miles south of Central London and 15 minutes from Gatwick Airport).
Brief Description
This car was built from 1990 in the style of the Alan Mann 1966 GT40, dark blue with centre stripes and rear deck air-intake scoops (white stripes since removed but can be reinstated if required) then highly developed by the Porsche Racing Driver and Race Development Engineer Neil Bainbridge (now www.bsmotorsport.co.uk ) in response to ongoing testing and racing. She was raced for five years in the Sports GT Championship, Super GT, Super Sports, Winter GT, Special GT with a foray into the Brighton Speed Trial and FIA World Sports Car Championship. Her condition may be described as ‘patinated’ or ‘battle scarred’ in that she bears the superficial scars of her racing exploits even back to catch-fencing days which we feel are full of character and she's constantly being mistaken for an original; however, all can be quickly and inexpensively repaired.
History
She was placed second in the 1995 Sports GT Championship, third in 1994 and fourth in 1993. Other awards associated with myself and this car are; 1994 Driver of the Year, 1993 Spirit of the Championship Award with short-held lap records during those years at Oulton Park, Snetterton and Donington. The car was sold in 1996 and was then used by Hans Frietag for track days and car shows until I bought her back in 2004. The engine was refreshed and a chassis-up rebuild completed in mid-2005. Other than testing and an outing at Spa Francochamps in September 2005, following a major refreshment, the car has remained in a Carcoon www.carcoon.co.uk
Why selling?
Having children in later life whom are now six and eight we have recently decided to down-size, moving to the country and reluctantly accepting leaving motorsport at this level but will leave more time to spend with our daughters and our love for vintage Bentleys in a slow quieter environment.
