Your insurances in the UK seems bonkers. I pay something like 60-65 pounds converted from DKK per month for my Seat Leon and is covered 25000km a year, I have 0 self pay for damages causes by others and 250 pounds converted if I am at fault(but only to my own car, others are covered with no charge to me), no matter who drives the car if something happens to them and they get disabled then they are covered, if my windows get a chip or is destroyed then its covered for free unless its the front then I have to pay the first 120 pounds myself but only if its a complete replacement and it can't be repaired. Anything can happen to it, don't matter, the insurance takes care of it, heck almighty God could decide to smite my car and its covered. The price has been the same for my old car ever since i got that and my new one only increased the price due to increase in horsepower by around 15 pounds.
