things to check when viewing -
when you press the 4wd button the dash light should flash for a few seconds while 4wd engages and should then show a solid light ( non flashing) to indicate 4wd has engaged as it should, if it continues to flash then the 4wd system has a problem and wont of fully engaged . you may need to be moving ( but thats not necessary) for it to engage/disengage which is perfectly normal but only test that by moving in a straight line unless on a slippery surface.
if youve not driven a fronty 2.2 petrol before the temperature gauge should sit at approx 85deg however if in standing traffic for any length of time that will soon rise to 100 deg, just before that point the electric fans will have cut in ( at low speed) and cool it back down to 85ish again ( this can be checked when warm and with the bonnet up after youve taken the test drive

) if you are sitting with it running especially in the warm temps we are having now the needle will be up and down regularly, i found that quite strange after having had fords for much of my driving past ( they never moved lol )
finally get underneath and check the chassis ( ive seen some which are pretty rusty, probably caused by launching boats etc ) and rails especially the 1 tucked up behind the rear bumper that would rust first if at all, apart from that all the normal checks you would do when looking over a car
good luck on sunday
