Thanks for the message.
It was 6:30 am having woken up to go to work and it took a while to sink in. I actually thought I had mistaken where I parked my car at first but then it slowly sunk in. As I ran out to check I could see what I thought was snow/frost on the ground was actually broken glass.
I'm insured and are going through the process of claiming for the lost. I'm thinking of either getting another 3 series M Sport, hopefully in Le Mans Blue again or black, with a bigger engine and more gadgets in the cockpit! Or I might go for a 5 series instead. My next car will def be fitted with a GPS system, a siren added to the alarm to deafen any wannabe thieves, and lock the wheel at an angle when I park it!!
