Here is my fucking awesome review (based on only pictures) of most of the major manufacturers who showed up.   
Acura: Stop rubbing the ugly off on the Hondas.   
Audi: Your shit is too flashy. Tone it down before people give your buyers the same assumptions as BMW owners.   
BMW: What the fuck is that 535i? It looks like a X5, which is about as useless as your electric cars. I like how the Sedans looks have gone back to early 2000's.   
Cadillac: Oh look, its that car that looks like every one of your cars.   
Chevy: Whoopee! A Corvette! Who the fuck cares. Wheres that electric car you promised?   
Ferrari: No one cares.   
Ford: Thumbs up for everything but that green one. I like the new focus, especially the RS with its "RevoKnuckle" suspension, which literally turns the game around with FWD handling.   
Honda: You need to get rid of those blind designers. Your cars are good, but I have made shits more appealing to the eye.   
Kia: Quite a improvement.   
Lexus: That LFA looks nice, but its still too much money. That green car looks like one of my stools after a lot of guacamole.   
Mercedes: No one cares.   
Mini: That offroad thing made me lol.   
Mitsubishi: GTFO   
Nissan: GTFO   
Toyota: That Tundra pull out bed is pretty awesome. The electric concept interior is just plain wrong.   
Subaru: I like that gullwing concept, car looks very spacious for its size. Ride height looks like it would be a serious drawback with a full load of passengers.   
Volvo: I am disappointed in you for having fucking TWILIGHT in the background. I literally hate how Volvo got associated with that shit. See pic below. (Is that the new S60 in the background, below the fagginess?)   
VW: Just keep doing your thing I guess.
