Well, the trick I see is not sending/receiving the messages ,but cracking what they mean. There is no standard for the application layer, and I'm certain that manufacturers make at least some kind of effort to encrypt it or to at least make it "fragile", meaning, that any goofing around will shutdown the system (go into limp home mode, for example).

It would take extensive "spying" and recording of an identical operational car, then analyzing, then copying the messages and programming them into a controller. and verifying that the messages do what they are supposed to do (which might be scary).

The controller part is actually pretty easy, there are 8051 based chips as well as PIC chips. Both have compilers, including BASIC compilers (!), cheap or free.
