[The Deuce]

Move the battery to the trunk, and put a kill back there. I've seen hood locks that attach inside the engine bay, so you can't tell from the outside.

I've heard nothing but good things about lo-jack as well. There was a chop shop down there that got busted with like 20 cars in the various pieces. It was busted up by them snagging a car with LoJack, and it was the only one that could be driven away.

Something to think about.
