General Motors will be finished building the new "First Car" at around the same time that Obama will be taking office in January. The limo will actually be truck based Cadillac that will replace the one that’s been in service since 2005.

Not much about the actual specs is known of the car but educated guesses have led people to believing that the car can withstand fire from assualt rifles (at least). I would also guess that the limo has it’s own air supply in event of a gas attack.

It is also presumed that GM is building several of these presidential limos to act as decoys for further protection of the Commander-in-Chief.

I wonder how the finished product will compare to Knight Rider’s KITT?
