Cadillac.com has an interesting Flash interactive overview for the XLR. You hear the voice of the engineers and designers as they talk about the exciting features. For example....heated AND cooled seats! They stressed the "intuitive" environment of the XLR and how it makes you want to touch everything inside as soon as you sit down. There is no key, just a little gizmo you press that grants you access to the car, and then you press a start button. MAN i want one!!
