At that mileage budget for an Autobox oil change if not done already..
The TDV8 has a habit of eating intercooler hoses, usually a nice split right where you can't see, when you hoof it there shouldn't be any WHoosh noise
Check the coolant at the beginning and end of a good hard test drive, if it drops expect it to either be EGR coolers or Hedgaskets..
To that end check the coolant, look for any foreign substances, i've seen a few that have been Steelsealed, and this shít is satan, it turns to turkish delight and blocks the rad, it usually hands around in the expansion tank too, it is a bodge for coolant loss on the TDV8 and a pain in the ass to flush out..
Performance should be pretty good, mid range pull is what you want with 640nm at your right foot, it shoudln't be slow, if it is slow and/or stuttering expect EGR coolers and or split intercooler hoses.
Turbos are another thing the TDv8 likes to munch, give it the hoof and look for any blue smoke out the zorst, there shouldn't be any..
If you see anything untoward expect the worst the 3.6 is a fickle beast, little issues mount to massive ones in a short space of time..
Not my engine of choice personally far too complex and with little spece available the engine usually has to be almost stripped to do even "normal" jobs..
