Try to make sure it has matching tyre brand/model all round, however, it may be too late for you to do anything about it now
Check to see who the previous owner(s) were, if you see the name ERAC UK Ltd then it belonged to Enterprise Rent A Car
Other than that, the usual stuff really, condition of car, test drive (make sure the wheels are balanced, so try to get up to a decent speed), check all the toys work!
Hopefully it will be a smooth process for you and enjoy your new car
