£15? I can see what you mean you are extremely generous, do you have the details of the garage that does the tracking for £15? Might start using them myself.
You must be new to the job.It does not matter what you may do to improve your image,be it promoting yourself for sponsoring good causes or offering some no quibble free repair policy,you will still be viewed with suspicion.Get used to it.
Only last week my Mum decided she didnt like the bumper on her 17k mile 2010 KA Zetec, I kid you not the OSF bumper has scuffs and a small crack but they wrote it off. Shes 85 and actually decided to hang up her driving gloves and take the £3900..
Salvage price was £1130..... well it seemed rude not to. Plenty of preloved in colour genuine bumpers on ebay for £150 ish and a mornings work should sort it.
Never ceases to fail me what insurance companies deem as a write off
