Fast Lane Daily Spies Cadillac CTS Coupe, Cornucopia Of GM Products Fast Lane Daily's insomniac spy photographer, Keith, spotted this abundant collection of General Motors products taking a break from some high-altitude testing in Colorado's Rocky Mountains. Most obvious is the 2010 Cadillac CTS Coupe , but also tagging along were a couple of small hatchbacks, one of which looks to be the 2011 Chevy Beat . One shot even shows what could be the 2011 Saturn Aura , or perhaps just the European Opel Insignia. All that and more in today's episode of Fast Lane Daily. Video after the jump.
