AMG and co “only for export”? What is this about?

Hello MT, again and again I come at mobile.de to actually very expensive cars which are offered for a mock price. For example GLE 500 Coupe for 31,000€ or an M2 comp. for a similar course. The mileage is always very low and optically the cars look like new. But then always stands there “only for export” According to Google are such vehicles with which the dealer is afraid to give, but this always refers to old cars with extremely high mileage and a completely different But what about these almost new cars? Are they really close to exitus and very expensive repairs would have to be done? Maybe someone knows that?
