Hi DR_D
I think it the same for all used cars , I first have a look at the overal body looking for panel damage/door gaps & over spray (in the door/boot openings) but take your time go round the car 4 or 5 times , As this is a car that can be a pig to reverse check the rear qtr panels (i missed it on ours , But it was repaired very well). Check Wheel (Rim) damage , I would try & get as low mileage as you can , Engine as normal check of leaks etc ,try to hear the engine cold & warm , Tires for the rears are about £150 upwards each . Ther are loads of Xfire for sale up & down the UK so you could get a great deal at the moment . Just wish i'd waited until now to buy
Cheers
Andy
