Is buying a high mile Mazda6 2.2D a bad idea

Posted in Jap chat also but as there seems to be not much activity over there I'm posting here too.

I'm selling my E46 M3 as I need something with a decent boot and my annual mileage will be increasing soon.

As such I've been looking at estates for around the £5k mark.

The vast majority of my car history is German and the wife has an Octavia VRs so fancy something a bit different.

For a second I was tempted with the 270 BHP CX 7 but the fuel bill would be similar to the M3 so I saw sense and dismissed the idea.

Anyway. The Mazda6 Estate seems to fit my requirements nicely. They seem decent value for a 2009/10 when they get to 100k miles or so. Are well equipped and look decent.

I've seen a couple that I like the look of. The first one is cheap. I suspect due to it only having part history.
Is this too much of a gamble even at this price?
What do I need to look out for with these cars?

Or is there merit in spending a bit more and getting something like this?

Or is the 2.5 petrol the way to go if I can find a decent one?

Thanks

Love the look of the Mazda 6's,Although I believe the Mazda diesels have problems with the DPF's blocking up,So unless you're doing a fair bit of motorway mileage there are probably better options out there.Although the 2.5 petrols are quite appealing if you can stomach the fuel bill.
If it was upto me i'd be looking at the 07/08 Toyota Avensis or Skoda Octavia VRS if you can find a decent one within budget.

Look up chain stretch, injector seals, carbon build up and oil pick up blocking.

I got one with 74k and fsh, within two months it died. Lovely car but I wouldn't personally unless it has the chain done and injector seals done. Even then....

Maybe I'll look for a 2.5 petrol then.

There is a fully loaded 2.2d Sport on AT for £3.5K looks nice but only has part history. Everything I've read says don't even consider it. BUT Something somewhere in me wants to take a punt on in it if it can be had a bit cheaper.
