If anyone's registered or logged into the Lexus Drivers site, they've likely stumbled across the "Rewards & Events" tab, which lists many exclusive offers (such as free parking and discounts) for Lexus owners. Has anyone tried using these? Any thoughts on the experience/process?

I'm tempted to try some of them out, but find it a little obscure that you just need to show your Lexus key to an employee who'll supposedly know exactly what to do.
