Our 57 1.5 Clio was mechanically bulletproof and we never had any problems with it.
The electrics were mostly fine, except for the fact it enjoyed blowing headlight bulbs, and with inaccessible headlight units, meant a £80 trip to the garage every time!
Also, number 4 on the fan speed controller seemed to never work, even from brand new, unless in a Renault garage being looked at expensively.
When it reached 6ish years old, and at about 110k miles, the radio decided to break, but a cheap replacement from the local Halfords sorted that.
The only reason why we got rid of it was because the engine was a lot louder, and there was a strange vibration throughout the car. Mum said that the vibration and sound of engine were very similar to when the engine mount broke on her Mini a long time ago, and since it'd reached 120k miles, mum decided to get rid of it anyway because we could feel some ruinously expensive bills coming up
But y'know, the family and I would definitely recommend the car to anyone else wondering about it.
The only reason we didn't replace our Clio with another Clio was because the boot wasn't good enough for our grandmother's wheelchair, which is a issue that probably won't affect you anyway.
