*****UPDATE*****


Insurance Engineer has just rung, and I must say what a breath of fresh air. A very knowledgable chap who'd obviously done his Honda Beat homework!
The car isn't a 'write off' it is an 'uneconomical repair' as his estimate comes in at approx £2900.
He has suggusted that I consider a 'cash in lou' payment for repairs. Basically they pay me £2000 to effect the repairs myself. He is happy that the car is repairable and doesn't need to inform the DVLA to have a catorgory added to the log book. If I refuse the car will be sent for salvage and he estimated it's value between £3750 and £4000!
