Men In Black 3 ( MIB3 ) is going to be another great MIB movie, and in this one, J and K ride motor wheels!

 Looks like they are strored under and inside the 66 Ford (Fairlane?) for quick deployment

the Steve McQueen dune buggy from "The Thomas Crown Affair" , Faye Dunaway looks like she's screaming every time they caught air

I felt the Steampunk desire today, So I watched "Steamboy" and grabbed these screen shots, cool movie, just make sure to select the language options of your native tongue and avoid reading the whole thing

 any movie with a motorwheel can't be bad. A steam powered one is even better.

 Good kid has a runn in with the bad guys trying to steal the plans and prototype his inventor dad and grand dad sent him, and the kid tries to escape, using that motorwheel, gets chased to a locomotive, which gets attacked by a blimp ...

 later the bad guys send out an army of armored soldiers, and this aeronaut

who all are engaging in a war with the british who have these cool old tanks. The time frame is Victorian, and before any vehicles but the trains and tanks. 

Leatherheads, the movie, had some great vehicles from the 1920's... George Clooney driving a motorcycle and sidecar, and Rene Zellweger. Good movie

 I looked carefully at the motorcycle, and can't see who made it. Could be any of several bike companies

"Cars 2" movie from Pixar/Disney had a lot of small details of conversion to automotive looking architecture

 they call it Big Bentley in the movie

 They were right smart to label it Holden

 Leave Spring under the above bridge, and replacing the cables in the London Bridge below

 through out the movie you'll see statues of cars instead of people

 I totally dig the wire wheel in the Eiffel tower, could be based on Kelsey Hayes, but who knows

 the side of the Notre Dame looks like an exhaust header

 A valve cover topping the Arc De Triumphe

 a piston for an elevator

 A Boyce Motormeter in the above building

 the light shade looks like an type of engine

I didn't see all of these the first time or the second time I watched the movie... but I saw a lot of them, and found the rest when looking for them specifically for this post
