Man! That sounds like one secure ride! I don't blame you for not giving up all your secrets!
That security film. . . Is it clear, or tinted? I've never heard of it.
I'm still debating whether I'm going to transplant my stereo from my water-pumper into the beetle. If I do, I'm definitely going to put the CD player in the glovebox.
I had a friend with an old Landcruiser that had a wire hanging out of his dash that looked like crap. Only thing was that you had to touch that to a certain small portion of the dash to start the car. That was pretty ingenius. (I thought)
So I'm trying to come up with some clever ideas like that, but hopefully a bit cleaner!
