ouch. you can get a cover note from insurance companies you know!
really feel for you, that sucks especially since you've done nothing to deserve it other than having a fine taste in cars. It sounds like whoever did it was malicious and hopefully has their next life as a tapeworm.
You must have bad crooks in guildford, when someone tried to steal my R31 the only thing they broke was the ignition barrel. No smashed windows, they even unscrewed the steering column surround rather than smashing it. Good thing there was an immobiliser tucked away, if they'd found the switch it would have been gone. Only had 3rd party property on it too, was not worth insuring comprehensively!
