What faults should I look for on my new CLS AMG?

Just bought a 05/55 CLS55 AMG with 58 K on it, full MB service history, just serviced.
Only extras apart from the usual AMG stuff is keyless go and garage door opener.
Anything in the recent horizon I should be aware of?
Any common faults at 60kish?
I'm trying to work out whether to get a warranty or take the chance and these answers will help me decide.
I do around 6k miles per year.

I'll upload some photos when I get them.

Thanks Colin.
