Mercedes CL500 ( C216) - Buying Advice Please

[lambo_xx]

Got a friend who is looking for an early one of these with approx 60k Miles (Prob 2007/08)

I don’t know a huge amount about them so I've got a few questions?
What are they like reliability wise?
Anything in particular to look out for?
Did they all have the night vision camera on the instrument binnacle?
Were massaging seats an option?
Is there an ipod cable/aux/USb etc?

Thanks in advance
