Holland Import buy Xpeng G9

Good day Together, I have the opportunity to buy an e-car (X-Peng G9). The car was bought as a new car from a Dutch dealer and registered for the first time in Germany. Now the owner wants to sell the car. For me as a layman there are several questions. The car has a guarantee until 2030. Does this also apply in Germany? If so, is the process easy or can it be that workshops refuse to do something? What about the resale? o was minimally cheaper in Holland. I just don’t want to stay on the car in a few years because nobody buys an import.
