124 series E Class , help re:buyer pitfalls

[shoee]

Hi

I'm thinking about buying a 1993-1995 E class Auto estate, probably 200 or 230, basically it is a second car for family transport, probably only do 7-8k per year and keep for 5 yrs min.
Looks like there are lots in the 70k to 100k miles around £4-6k. Have been told they run on for ever, very reliable, last of the really well built cars etc.

What are the things to look out for on these cars, and what are the major expense areas ?

Would they be much more expensive to maintain than say a Volvo 850 ?

Any other help/advice much appreciated

Peter
