The 2004 Cadillac CTS-V Race Car, manufactured in Wixom, Michigan, is a distinctive creation by Pratt Miller Engineering in collaboration with General Motors. This high-performance vehicle, first introduced in 2003, was designed as the prototype for Cadillac's entries in the SCCA World Challenge series from 2004 to 2007. Powered by a formidable 6.0-liter LS6 V8 engine coupled with a Hewland five-speed dog-ring manual transmission and a limited-slip differential, this race car boasts impressive power and precision. Currently active and fetching $11,000 in bids on Bring A Trailer, it's a thrilling piece of American racing history.
