No F1 car lasts an entire season though. Whether practice, quali, or racing, it’s going to get damaged to the point it’s no longer usable for their purposes (going as fast as possible; serviceable to the ordinary schmoe - maybe). Not to mention the upgrades over the course of the season. The monocoque they finish with is generally not the one they started with.
