The 2 photos above were taken at Volkswagen's new storage facility in Wolfsburg, Germany. The actual space that the facility occupies is approximately only 20% of a comparable facility with the traditional design that is used primarily in the US. Not only is the German structure less expensive to build, but vehicles are also "retrieved" in less time and without the potential of being damaged by an attendant. Collecting your new car is an event in itself.
"In a fully automated procedure, your new car is brought down to you from one of the 20-story Car Towers. Large signboards in the Customer Center show you when your turn has come. Then, you're handed the keys, your picture is taken, the glass doors open and your brand-new car appears. You're all set to go".
