OK time for my comments... Ive had my 1.2 since November - my first car - and have just hit 9k miles (!).
First - the loosening up that solow refered to (nothing to do with my mum...) I agree with - the car has definately been running smoother and slightly quicker in recent weeks.
Like many of you guys (or so it seems) I test drove many of the small car offerings before purchasing, and I dont have any regrets about the Clio whatsoever. Ive actually just come home having driven for most of the day, in a huge variety of scenarios, and I must say Im absolutely chuffed to bits with the car. To give you an idea (this was all today - Friday):
1) spent much of the day on dual carriageways / motorways including the M3 and A34 Winchester-Oxford, typically cruising at 90 which is smooth and feels safe. I touched 100 though it started to feel slightly shakey, I always ease off at this point because I hate to think of the car suffering abuse!
2) had some great drives down single-track back roads in the Cotswolds (because the A40 was gridlocked with hol traffic!!) and also some great winding roads in the Forest of Dean and the A338 between Swindon and Salisbury. The Clio was a pleasure to drive in this scenario, nothing really more to say!
3) several challenges on Cheltenhams inner ring road this afternoon!! A notorious boy-racer infestation in this, my home town... so I was amused to have several try it on... including one in an Fiesta with 16V badges all over it which, to my surprise somewhat, I absolutely murdered... I say surprise because Ive never really raced before, and it was very clear that the competing muppet in this case was really trying his hardest.
Sorry I cant be much more technical or specific, I just wanted to say that from a first-time drivers perspective, the 1.2 16V is heaps of fun and better than everything else in the class!!
