"Hi, there. A few things to remember about our free double upgrade offer. First, it’s awesome. Second, it’s valid on advance reservations made for an Economy through Intermediate size vehicle at standard daily or weekly rates at participating locations within North America. Find participating locations by calling 1 800 rent-a-car. Whew. Okay. Moving on. A 26-day maximum applies. Rental must begin on or after 19 August 2010 and end on or before 20 September 2010. The upgraded car class will not appear on your reservation, but we promise it will be applied upon arrival if there’s an available car in the next two higher classes free of charge, naturally. Also, this offer can’t be combined with other coupons, offers or discounted rates. As you might imagine, standard rental qualifications apply. Other restrictions, including holidays and blackout dates, may apply. Pickup and drop-off service is subject to geographic and other restrictions. What else, what else? Oh yeah: Void where prohibited. Now, that wasn’t so bad, was it?"

More T&C need to be written like this. It answered my questions, and was fun and made sense. If only I needed to rent a car.
