Hmmmm, well yeah if it was a deceoticon, or a constructicon for that matter you definantley would have seen some sort of symbol on it.

So i guess it is prolly used as a prop arm for a TF in the movie smashing the SUV

They did basicly the same thing in fantastic4, the scene wear the "Thing" smashe's the big rig, and instead of CGI destruction they ran the 18wheeler into a post.

So yea this is probably resembleing an arm for a TF

 

Either that, or the Constructicons *really* are in the movie.

*opens enormous can of worms, runs and hides*

 

That crane has nothing to do with anything, I would guess.

It's not a TF, just a prop or stand in for a TF IMO, NOT a constructicon or whatever.

 

it sure is hard to mod these threads and not get spoilt  

 

i am pretty sure its a stand-in.

you can see some sort of framework instead of the "shovel" part that is usually on the end of a backhoe.
there are also additional hydraulic and/or electrical cables going up the arm of the backhow. (they are loosely draped by the joints)

i think this will be used to perhaps "smash and squeeze" the SUV, to make it look like its being grabbed by a transformer.

this is all educated guessing, since the pic is too far away to tell if there are hinges and actuators on the framework to make that happen.

but thats my guess.

as for the interceptor/mustang = brawl confusion...
wasnt there some pics floating around of an interceptor with a decepticon logo on it?
leading people to believe maybe brawl goes through the same process as bumblebee?
i've been trying like heck to find the pics but i havent been able to find them.
i'll post when i do.

seems to me, a lot of the misunderstandings on this thread have been due to lack of communication due to grammar and explination.
yes, that link of brawl was a mustang. but the link was for pics of bumblebee that happened to have a pic of brawl IN them. the police car in the backhoe pic IS indeed a ford interceptor and very common. but im not ruling out the fact that it *COULD* be brawl.
