Lot 4 (Into the Groove, 9th July 2019)

1987 Corvette Callaway Twin Turbo

1987 Corvette Callaway Twin Turbo
Registration Number: BSB3775 (Texas, USA Registration)
Chassis Number: 1G1YY2185H5108293

The Calloway Twin Turbo was a very high performance alternative to Chevrolet's standard Corvette. Offered by Callaway Cars under license from Chevrolet between 1987 and 1991, it was available at Chevrolet dealers by selecting a special option on the order specification sheet. The car came with normal Chevrolet warranty as well as an additional one-year 12,000-mile warranty from Callaway Cars. The conversion cost a massive $26,995 over the price of a base model Corvette and consisted of taking the engine out of the car and performing extensive modifications along with installing two turbochargers. Making over 380bhp, over 500 cars were subject to the conversion. One derivative of the Twin Turbo Corvette, the 880 bhp Callaway SledgeHammer recorded a speed of 254.76 mph making it the fastest road-going car at the time.

Presented in metallic silver with black leather sports interior, the car is fitted with a six-speed manual gearbox. Paperwork with the car suggests a number of special options and upgrades were later made to further improve performance and Toyo Proxes R888 tyres are fitted.

Mileage is recorded as 14,757 and a file containing various documents, correspondence and Calloway Owner’s Manual accompanies the car. Included in this documentation is a photocopy of a C&E 388 form dated July 1993 suggesting that duties were paid coming into the UK at that time, although the vehicle does not appear to have been UK registered.

Buyer's Premium for lots 1-10 will be at the reduced rate of 15% plus VAT.

Sold for £9,000
