No parts available

Do not buy a VW Amarok. I took my VW Amarok to have work done on my gearbox. The company advised me that there is no aftermarket seals available they will have to order it from VW themselfs. I ordered the seals from VW myself. They advised me that it will take a couple of days to get the seals as it must come from Johannesburg, but one the seals is coming from Germany. Two days later i contact them again to get an eta on the seal from Germany. They inform me that they can only get the seal in September that after i had to pay them upfront to order the seals for me. How can you sell a vehicle without having stock of a normal wear and tear item like a seal.
