i have a physics professor with a 60's model camaro but he put his own security device, kinda unconventional though...

He had a steel canister facing outside the driver's side at the feet with a few inches of explosive wire inside attached to a detonater that went off whenever some1 opens the door... it would literally blow the shoes off the crook that tried to open that door. it was a fun idea, maybe if i take more classes i can do something like that.

not with explosives though, you have to own a claim to get that wire... maybe with pepper spray on the roof where that long plastic strip is at... that be fun, till it goes off on me
