if a car theif can get through a disklok- they deserve the car !!
the diskloks are great- cost about �65-
you can probably get them cheaper though now-
i have had the same one for years and i can highly recommend them.
i know a lot of people with expensive / performance cars and they all have one of these.
the idea is the car theif sees a disklok - then goes to find another car without one in- sad but true.
