Hi all, any views on the above cars? Look like a nice place to be. Asking for my bro looking for an estate under £9k.

Look into subframes and timing chains.

I understand that Merc usually cover the cost of the replacement of the rust-from-the-inside-out rear subframe.

As I suspect the engine is the Evo version of the M271 with a turbo rather than the earlier supercharger, then I gather there are different* issues with the timing chains etc. I note it does have direct injection and if it is pure direct injection, not a combination of port and direct injection, then you may be getting close to some coking up of the inlet valves.

*edited to change fewer to different

Not sure of exact prices but the subframe would be towards a couple of £K and the timing chain probably a bit more than that.

As said above MB often (but not always, it seems quite random) replace the subframe as goodwill. I would tend to think that as these cars get older and as the one linked has had a few owners, that it could be tricky. It's also possible it might have already been done - it's an issue that it really isn't obvious as they rust from inside so they can pass MOT (even at dealers) and then break a few mths later.

I had a diesel which have duplex chains so I'm less clear on the chain, tensioners (and coking) issues - I just mentioned them as something to be aware of as they seem to crop up a bit on the MB forums.
.

I'd also say have you got a trusty Merc indie nearby? You ideally need Merc diagnostic kit (or something similar) for these cars otherwise you're shooting in dark with any issues that crop up.

I see that car has an astonishingly clean MOT history! I know prices have gone a but mental but is that really how much these cars ar at 13yrs old now?

A couple of years ago I sold my 2005 C Class Estate that I'd had since it was 5mths old for £800 - every MOT for the last few years had a massive list of advisories. I thought it was just the mental indie but I looked since and its last MOT was similar - in fact with some new issues too.
