Not sure if your still looking for a Clio but this may intrest you if not to far away.
We have had a Clio 200 traded in and know the background of it. Its one of our saleman friends old cars...
Working in a dealer you do see shocking work done by other garages outside the dealers and and then the car arrives with you and you can see why the garage cant fix it due to the lash up they have done trying to bodge it back together without spend money where you have no choice but to spend...
I have to add this as it touches a nerve when reading shocking threads and every dealer gets brushed due to one dealer.
But before slatting Dealers over 1 dealer maybe its worth doing a bit of shopping around and trying dealers that have customer care/service and look after the customers...
This is the machine i use

Is a normal water pump nothing special we keep them on the shelf. Only thing i can think is they sold out but if they knew you were due in for the work this shouldnt be the issue.
