So here in the states we have a trade publication that the insurance companies and other motor vehicle agencies use to verify a car or motorcycle and so on.
as per wiki
"The company reports market value prices for new and used automobiles of all types, as well as RVs, motorcycles, snowmobiles, and personal watercrafts. For new automobiles, KBB provides information about a make's MSRP, dealer invoice price, and a vehicle's New Car Blue Book Value; what others are paying for a new car this week. For used cars KBB provides retail value, trade-in value, and private party value. It obtains retail pricing by collecting information about actual retail sales"
