That's not how big corporations generally work. VW has interests in pretty much every country on earth, they sell NEW cars not used cars that were involved in a scandal. This is not a case of reselling a refurb TV or demo fridge If I were a share holder I worry about the net long term, VW will make those numbers back. Truth be told they are starting too.. I'd want those cars gone ASAP and the aura gone as a share holder. The biggest hurdle by far is the US has to approve the cars for export, which they likely wont
Here is the biggest problem. what are you are going to sell those cars for after they have been sitting for years(It's been over a year since VW started the buy back) in the sun(Those cars aren't protected from the sun or elements in anyway) refurb, shipping to the dock, loading on the ship and repeating the process? even at 10K CDN a car resold the money recuperated is a drop in a much larger bucket, thats if you sell all cars. They have already wrote off nearly 26 billion dollars because of diesel gate.
There are many third world nations that are trying to clean up their image (yea I know) they will simply refuse a shipment of "tainted" cars. However VW will gladly sell people in those nations new cars.
Here is my take on why they picked Victorville. The soil is perfect for aircraft storage and the weather is pretty good all year round. It's also already setup to handle large pieces of scrap.. Victorville security is excellent too. When an aircraft is put into longterm storage they are prepped, wrapped in UV resistant film and stored. VW likely needs to keep all the cars until the court cases are over, once that is over with the cars will be scrapped on site under court order
