I know Bumble bee is going to start out as a 1971 Camaro and then rebuilt as the 2009 camaro, Optomus prime is a Peterbilt truck, Barricade is a 2006 Ford mustang police car, Ironhide is a GMC Topkick C4500 4WD Crew Cab Pickup, Jazz is a Lamborghini Murcielago, Sarscream is an F-22 Raptor, Vortex is a MH-53 Pave Low Helicopter. And Ratchet is a Hummer H2

Heres some links with pictures

I prefer the beater camaro myself, although the Mustang Police car is pretty cool, I thought ratchet was an ambulance? A custom International would've been a better choice

I can tell this is going to be a great movie. I never treally was interested in Transformers until now. Also, Ratchet is a custom H2 ambulance.

Here's a butt-load of pictures

They really should have included the Citroën C4 from the ad in this movie

or the 2CV from the spoof
