since one of the tag lines is 'Robots In Disguise' the Autobots should obtain new vehicle modes since they've been seen, and it would help them a lot against the Decepticons (use your head if you don't see how), they should switch to Japanese and European cars for these reasons. 1: Transformers shouldn't be used as a marketing movie. 2: American cars suck and more than 60% of Americans prefer Japanese or European (preferably German) cars. 3: BMW's and Lexus are better than any American cars in performance and design. 4: Transformers was invented in Japan.
honestly, i thought that the decepticons were cooler than than the autobots
try comparing what they transform into
autobots: camaro, solstice, gm pickup, hummer, and optimus
decepticons: F-22 raptor (the best), pave low III (wicked), tank (doesnt exist but not bad), shelby mustang gt police car (gorgeous), bonecrusher (the lamest of all), and megatron (dont know what it is but looks great)
it would be cool if the autobots transformed into something from the military as well or more elegant cars
PS. anyone know whatever happened to the police car (barricade) ?
