Sportscar365 reported that a racecar, what appears to be based on the 2015 Cadillac ATS-V, was spotted at Chicago O'Hare International Airport. Is this Cadillac Racing/ Pratt & Miller (of Corvette Racing fame, who also built the CTS-V.R) responding to the influx of GT3 cars in Pirelli World Challenge and the rise of GT3 globally?
