HELP - viewing car tomorrow c200cdi

[IceBoy]

Hi All,

Please could you tell me what to look out for, the car in question is:

2006
C200cdi
Auto
Estate
Avantgarde SE
120k - 1 owner, full history

I know it is not going to be fast but are these adequate on the motorway?

What shout I be looking for?

Thanks in advance
IceBoy
