[windy millar]

I recently bought a D3 SE Lux with similar miles and FVSH for similar money so I would say it is about right price wise, depending on condition of course.
I got aux and timing belt and pulleys done soon after buying it rather than leave it to 108k. I bought the genuine parts myself and got a trusted garage to do the work.
The squeaky bum moment came before I had it done after speaking to a Volvo specialist who said to check it had the modification done to the aux belt tensioner. Apparently the design of the tensioner changed back to a previous more robust design, which required drilling the block (anyone else, feel free to correct me on this!) It should have been done when the belt was replaced at 54k and thankfully in my case, it had been done. Call the main dealer that has serviced it and try to glean as much information on any work completed as possible as well as the modification.
Check everything works as it should electrically and on the test drive check for any odd sounds and that it pulls well through the gears and check carpets for any signs of damp as screens are known to leak. Any signs of uneven tyre wear which could point to worn suspension parts and be thorough viewing the car overall. It is always worth going through the MOT history while you get the HPI checks done on it.
I am sure others will chime in with more stuff that I have not thought of but take your time as there are plenty to choose from.
