OP, on relation to the issues to look for, I would look for:
Condition of tyres and if they are all the same brand and even ware accros an axle....ask why if not
Condition of the wheels, more an indication of the care liven by the owner rather than a technical issue.
Does the roof work properly, this an expensive bit to fix
The idle blip/revs falling issue.....search this as it is very common, but does not really cause a problem...but they do not all do it.
Inspection 2, and were you are in relation to this
Brake fluid change and again where you are in the cars service schedule.
Rear springs pig tails can break
Do the calipers work properly, it is a known issue for the near side front to stick.
1200 mile run in service.
The clutch rattle is characteristic rather than an issue.
Does it drive straight, the alignment is very easy to knock out....done that.
Excellent drive though, does both daily cruse and flat out blat toy.
