Feel for you mate - not just for being a forest fan of course but due to whats happened.
I went through a similar thing a few years back now - car parked at the dealers, they had it for a few days to diagnose a fault so was locked in the back - in fact in Nottingham too!
Nicked all the Nav system, including changer and control unit even! must have taken them a while to get it out. All 5 wheels went - spare being an alloy due to the brembo's on the front.
Not the best phone call from the dealer when they told me this, then later was told its not covered on their insurance .. but thats a whole new story.
Hope you get it all sorted.
