CTS Coupe caught testing - center exhaust is a go!

Car and Driver (my personal favorite in-print car mag) has caught GM testing the production CTS coupe. Of interest, a rear window easily as close to horizontal as the concept, the center mounted exhaust is still there, the body work below the door appears to be spot-on, and the wheels look to be heavily inspired by those on the coupe concept as well. Differences we can see already are slightly beefier side mirrors, the style of the exhaust goes from over/under to side-by-side, and we should expect the bumper detail beside those exhaust tips to be different than the very concept-y details on the car we saw in Detroit. Unknown is how faithfully they have done the tail light treatment and the overall rakish-ness of the trunk-lid (the disguise makes the production car appear to have a more upright decklid - but that could be part of the disguise. I, personally, can't wait to get my hands on one of these - but am awfully afraid I will leave the dealer with one once I do. Cadillac, make mine 3.6l DI w/ 6-speed manual, in Black Raven or Crystal Red... See all the spy shots over at: Car and Driver: 2010 Cadillac CTS Coupe - Spied
