Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
maybe hook up a secret camera in the car??? chance you could get a close up of face? that would probs be to dificult anyway
he will probs find the camera and take that
1,what train station?
2,remove anything worth pinching and leave it unlocked.
The best and legal 1 i can come up with is an alarm system.... or chuck norris with a BB gun, which ever is cheeper lol
get your friend to get a lift to the train station or get her to park it else where,or you could hook up some sort of alarm
ideas
1. get a spare car battery and hook up the negative to the body of the car and positive to a plate or tin foil behind the door handle. hopefully that will shock them (i don't know though, pretty sure i've been holding on to the car body and touched positive before and nothing's happened...)
2. get some poo and rub that all under the door handles
3. install some jets around the car hooked up to a pump which goes off when the door is opened. route it to a tank with
a. red dye
b. cat piss
c. pepper spray
