So I was just wondering now that I have been and gone and bought an E86 should I buy some sort of tracker for it. Has anyone here had a Z4 stolen. You know how it is after you have bought a car, constantly checking to see if it is still where you left it in the car park, well I do anyway, silly I know but it does wear off after a while. I would be interested to know if these do get stolen, should I be worried or just being paranoid. Cheers.
