Really sorry to hear about that, nothing worse than someone bashing your pride and joy and then not being decent enough to own up. We had a similar incident with a Freelander in a public car park, luckily a member of the public took pictures and reported it to the police, they chase the offending person and as they had evidence threatened court action for failing to report an incident and driving away, even though no one personally in our car. The owner then owned up and the insurers were force to pay out for our repairs, it took 3 months though.
I hope it works out for you,
