Jeep.com has a minisite and giving away some Jeep Commanders. It has a great intergration of Google Maps. The hot spots are small Jeep Commanders, clicking on one display the standard Google balloon but with video inside of it. After the video plays, it converts to a little cardboard box. Within the cardboard box you'll find discounts to Jeep products.

This must be the first "real world" use by a large corporation of Google Maps.
