My 22 yo DS has had a request from his car insurance underwriter for proof of all of his details. They want a copy of his V5, copies of his driving licence and the driving licences of the other named drivers on his policy. They want pictures of his car, front, left, right, inside, speedo, under the bonnet, in the boot. They were questioning him about modifications - he's had the car for three years, no claims or accidents. Why do they want all this info? Is this normal?
