I took RC's advise and test drove both the Porsche Cayenne Turbo and the E55 AMG. Very different vehicles!

I think I saw a lot more info for the driver around the speedometer in the Cayenne than in the E (e.g., what gear in automatic, fuel consumption, average speed). Am I correct?

The E55 salesman who seemed ot be in a hurry could not explain how to get info. I was using only one of hte buttons on hte left. I wondered if there were more buttons on hte steering that changed the info.

Also the owners' manual seemed ot be on hte web. But no more. It has been replaced by a puff piece. Am I correct?
