mk2 clio i assume? if you can find a 100 in your price range snap it up, if not 80's are still very good, rare though so you generally need to accept the colour/spec you get!
with 65's you get a choice of colours/spec because there is plenty about.
dont be put off with higher millage, look for a good service history, they are 18k or every 2yrs what ever comes first, more regular oil changes is a bonus but unlikely to find unless going enthusiast. they are pretty solid, there is a buyers guide on here somewhere by edde. Just make sure it has no warning lights, should pull thru the revs on full throttle without cutting power and throwing up lights (sign of the pump going)
Dynamique is definately the one to go for, from memory all 80's had AC as standard, i may be wrong though, rarer options to look out for are electric sunroofs, climate control, xenons, cabasse stereo, 6 disc changer under passengers seat.
