How this page is built: every figure comes from the registry and links to the offer page, where each value carries the day it was read, its source and a fingerprint. A price counts as moved only if it differs between the start and the end of the month and at least one real movement was confirmed in between; prices that bounce back are left out, and so are aliases such as "latest" models, whose price changes when the alias moves to another model. See the methodology.
