Contract withdrawal in the case of inflation?

Since the used car prices are currently so crazy, I think about ordering a new car. The current car is paid and will probably drive a few km without any problems. Therefore we have no pressure when the new one will be delivered at any time. I set myself up for a delivery time of at least one year (VW dealer spoke earlier of ~ 18 months), but also did not want to wait for nothing. What possibilities does the dealer have to return from the contract to tret We have 10% inflation next year. Are there clauses in the small print that the seller does not have to deliver in “special circumstances”?
