No. Unibody or not, the battery's negative terminal has to connect to 
the chassis somewhere. Corrosion can develop there. This happened to me 
two months ago. ECM hums along just peachy until I started this old 
animal. Battery voltage dropped and because a high resitive point had 
developed at the point mentioned earlier, the voltage presented to the 
ECM dropped below a value that would keep the ECM happy. So it rebooted 
as soon as I  stopped trying to start the car (and the terminal voltage 
recovered). Other intersting stuff happens, too, but I'm sure no one 
here is interested in that.

Cute.
