Just some info that may be of help. My son recently got hit from behind in his Clio. Guy admitted fault and details exchanged. My son called his insurance company and was told that they were putting him through to someone who could help.
He was put through to a solicitor. They asked him if he wanted a hire car, to which he responded he did. The hire car was dropped off and his car taken away for repair. 24 days later, his car was ready. He recently received a letter detailing various costs. The corsa on hire cost £72 a day + VAT. It would seem the new scam on the block is to take a minor damage accident and take an age to repair it. The car hire came to over 3k (including drop off and collection).
It was my sons first accident so he thought that being put through to a solicitor was normal.
I've seen an article in the one of the broadsheets that runs a story about Daren Bent, the footballer. He was caught by the same scam. He was put into an Aston Martin after his Merc got hit and his hire charges came to over £60k!!
