Don't keep it too long.
I – until last Friday – had a 52 plate TDCi LX like yours (albeit with 145k on the clock). I had DMF probs, wheel bearings wearing out, then endless problems with back brakes etc…
Basically, despite being an excellent car to drive, it got to the stage this year where I was paying out more on parts than the value of the car. Sad to see it go but glad I've got a newer car that isn't going to surprise me with something else wearing out every other month.
