The OP didn't claim that red cars were the most expensive, just that there was a surcharge for red which is true. I've worked for insurance companies here in Australia and the UK. Not all insurance companies ask about car colour but some do. I assume it would be the same in many other countries. I bet there's a hefty premium for Vantablack! https://www.bmw.com/en/design/the-bmw-X6-vantablack-car.html https://www.bmw.com/en/design/the-bmw-X6-vantablack-car.html
