I'm still chuffed to bits with mine, some 4 weeks in now. Don't worry too much about what you've read on here, the things you've mentioned are only minor niggles which you're likely to get with any new car, and are easily sorted by the dealer.

Like you, I was also tempted by the Clio 182 but having driven one I wasn't overly impressed with it on a day to day level (particularly as it was raining) and, tbh, where do you get to use the extra performance that the Clio offers in the real world? It'd only be out on a track where it would be any better. I was also genuinely shocked by the poor quality of the interior for what is a £14k car too.

Go with the ST, you won't be disappointed.
