Thank you Malc, from our latest correspondence they have agreed that it will be repaired by a Jaguar approved garage who have stated it requires a new bonnet, new xenon light cluster and the bumper is to be repaired. Hire car supplied until the repair is completed so to be fair to BCA, idiotic driver aside, they have been very good up to now.
Looking forward to getting our hands on it. Although it'll be strange after 5 years driving of an Audi TT.
