A championship-winning Cadillac racer with a V8 that has barely five hours on it is looking for a new ownerThe Cadillac CTS-V.R Coupe was used to claim three drivers’ championships. This example has a naturally aspirated LS3 V8 used for just five hours. This Cadillac CTS-V.R Coupe racer, one of just three ever built, is the type of car you’d expect GM to either hide away in storage for eternity or perhaps display in a museum. The racer was built through a partnership between GM and Pratt & Miller, created specifically for the Pirelli World Challenge GT Championship. A full spares package is also included in the sale, including spare pieces of bodywork, multiple sets of wheels, spare brakes and suspension parts, and new subframes.
