The new Caddie CTS model "CTS4" has a V6 that pumps out 300+ ponies, is AWD and handles like a BMW. I have been a muscle car guy all my life and I think the new GM V6's are nothing to sneeze at. The 4 banger they are considering for use in the new Camaro is also turbo charged and puts out gobs of horse power. Theres 2 car forums I visit regularly if you want the latest on Camaro and GM info.
http://www.gminsidenews.com/forums/ http://www.camaro5.com/forums/index.php Both are great sites and the Camaro 5 forum has tons of pics and even a few vids of the new Camaro. I read an interview with Bob Lutz recently and he said that people who see cars as an "appliance" are defaulting to Toyota and that GM was trying to position itself to provide cars to people that see them as more than a 'toaster'.
Back in the 80's Buick tried to remake itself to appeal to a younger demographic with their T-Type Regals, Grand Nationals and the Reatta. They got scared and cancelled all their fun cars and meekly went back to selling cars to the 50+ crowd. But then Cadillac was successful in reinvinting itself in the late 90's and early 00's. The Cadillac CTS, CTS-V and CTS4 have been wildly successful and have even gained a foothold in europe and asia. Heres an excellent Top Gear review of the Corvette V8 powered CTS-V. They run it to 163 MPH (!!!)

Granted I am a life long GM guy, my first car was a Chevy LUV, my last car was a Corvette, before the 'vette I had a Blazer and restored a '72 El Camino, my current car is a Buick Reatta and my next will be a Cadillac CTS, but I think General Motors has a chance as long as they dont lose their nerve, again.
