This year's show is from January 23rd to February 2nd. The list of Ride 'N' Drives this year is mostly the same - Cadillac, Kia and Mazda are particularly interesting, though Scion will bring the FR-S (like last year IIRC) and I like VW's TDI models. There'll be a lot of cars on display that I really want to see.
Several of the cars I'm looking forward to seeing this year are Chevrolets - I haven't yet seen the C7 Stingray and SS sedan in person, and I also want to see the Silverado, Colorado and refreshed Camaro. The C7 Z06 likely won't be there since GM didn't bring the C7 Stingray last year. The CTS, CLA, 4-series and refreshed R8 are some of the other cars that should be there and that I'm looking forward to seeing this year. I'm really hoping to see the 2015 Mustang, since they did bring the 2013 Mustang lineup to the 2012 Show a couple of months after it was announced. I also want to see the 2015 F-150, but I think Ford would be a bit too pressed for time on that one.
