Ill list everything I can think of but not saying they are all important some of them would have no bearing on weather you wanted the car or not. Apologies if you know all this already.
Check under rear passenger seat for water.
Check air con works, should be a audible cluck when it comes in.
Have a good listen for grumbling at the cam belt, a car of this vintage will be in the viechle range affected by a (possibly) noisy belt.
Have a good look at the paintwork as it will probably be Titanium silver. Rust speckles and peeling paint were reported with this colour.
A loud zinging above 5-6k is pretty normal.
Gear shift light will come on with ignition if it has one.
Has it got an alloy bonnet.
Warranty ? registered after 16/10/01 = 3 year factory warranty. Before that 1 year.
Alarm, LED will be at bottom left of gearstick on a uk car, sensors at top of pillars.
Look at how badly rippled the rear bumper is, catch the light right and you might see some dimples. Ive seen lots do it including mine, unavoidable but perhaps a bargaining point.
Look for moisture in the fog lamps (fixable) but Renault mod may not have been done.
Has it got two keys (new keys not cheap).
Service book says aux belt change at two years old, has it ahd it done or due soon ?
Has it got a spare alloy wheel ? Is the bottom of the well damp ?
Again appologies if most of this is irrelevant or already known.
