Need help...looking to p/up a 2010 CLS550...what to lookout for?

I need you help....as the title says, im looking at a 2010 CLS550 w/ 28K miles tomorrow...don't know what's in there...but what should I expect as standard equipment....and what are the options/packages?
Any issues that I should look out for? Noises/rattles? Engine issues? Suspension?
Thanks.
Pete
