Mercedes-Benz buyers can get one night free in one of 14 luxury hotels as well as two taxi vouchers to use while staying Stuttgart. You also get 7% off the price of your car. Air fare to Germany is on you, however.
You also get a free tour of the the factory and the Mercedes-Benz museum. As with all such programs, the automaker covers about two weeks of European car insurance, although you can pay for more if you want to keep driving longer. Shipment of the car back home and marine insurance, to protect your purchase on the high seas, is also covered. That's all included in the other programs, as well.
