Looking at a 56 plate facelift E320 CDI on 111k. What should I be looking out for please? It's high mileage - should that put me off enough?

Thanks

SBC - max number of pedal pushes (google it)
Front and rear springs
Folding door mirrors broken wires affecting the door mirror indicators
Voltage Regulator replacement on alternator (alternator is bullet proof but regulator is a worn part just like brake pads)

If you can get a print out of all current registered faults for peace of mind.

A 56 plate is probably a facelift model, so there would be no SBS braking issues as it was discontinued with the facelift.
I would check that the gearbox changes down smoothly from second to first, clunks are common with the 7G box.

If it is a facelift (and 56 is almost certainly from recollection) the SBC brake issue had been resolved by then, so no issues.

Early V6 diesels had issues with the exhaust manifolds which destroyed the turbo, but at that mileage it will either have happened already or is not applicable.

Inlet port shut down motors go, putting the car into limp mode. We have replaced one each on our two cars (a 56 plate CLS on 96K and an 09 E320 CDI on 75K) but on the E the inlet manifold was also broken, with a £2,100k repair (MB contributed, leaving us with £1,200 to pay).

Both cars occasionally will give a very uneven and lumpy gear change when slowing, but it is random and neither seem about to expire (famous last words!)

The CLS has broken every spring (and one actually twice). The E estates have self levelling rear suspension as standard, and it has yet to break a front spring, but we had issues with the rear when under MB warranty which involved new sensors, much tweaking and I'm not actually sure it is right now.

They are heavy on front suspension (bottom ball joints the favourite, going in as few as 60k miles) and pads, but otherwise seem pretty robust - we have had the CLS since new, and it is hard to see any real deterioration in the way it drives, or general solidity. There is no rust on either car.
