Service history. Check how often its had its oil changed, if its been on long life it could have been a few years between each changes, if thats the case the pickup/strainer in the sump could be a bit blocked with crap which can lead to oil pressure issues/warnings. Mine was on longlife but the previous owner had it oil changed yearly and the strainer was near spotless (i wasn't to know this but got the garage to change it with the oil change being due anyway).
A general check service history wise as it maybe due its cam belt, water pump and thats a few hundred £ to factor in (or get knocked off). If its not been owned by an enthusiast chances are the cam follower has never been checked or replaced, these aren't on the service. Mine got changed at 73k for i believe the first time and it wasn't caput but had plenty of wear. Not expensive and a guide on here will see you right.
Check the aircon works properly and goes ice cold.
Tyres - see if they are a good brand and all match, often a good indicator of what budget the car has been run on.
Check the spare wheel area under the carpet for water, often this can be the boot seal or the rear light seal.
HPI check incase its been binned or stolen. Check panel gaps around the car for anything which looks either really small or large.
Hope this helps
