I'm back from vacation and Sixt MUC gave me a nearly new black BMW 530d on my LDAR rental. I tried to get an AUDI A8 on the phone and at the counter but they couldn't find me one.
The BMW was a lot of fun in the Swiss and Austrian alps with the sport mode and Dynamic Traction Control on. I saw an Audi A8L in a parking lot and it was a beautiful car but I'm not disappointed. I only got to open up to 170km/h on the German motorway north of Munich before hitting construction traffic.
