E 220 CDI 2004, want to buy?

[Qamar]

I have W124 E320 1995 Station wagon which has proved to be a very good car. Well one of my friend who works in a rent a car business is recommending me to buy the above subject car. (E 220 CDI 2004). The car has done 425,000 KM. I know the mileage is very high, but even then when i drove it was just like a brand new machine.

Any views will be appreciated as the car has done a lot of mileage. Or if someone still recommends to buy it then what are the things which should be seen in the car.
