I've had a Cooper and a Clio 182 and have to say the Clio wins all round in comfort and speed. Having a work green car scheme whereby you are paid by the amount of CO2 emissions your car has, unfortunately meant the Clio had to go about 3 years ago. I have very fond memories of it. I then leased a Titanium when the Clio was sold and it is a better car than the ZS, no question. Shame I couldn't afford one at the time when the lease was up on it.
Having also owned a Clio 182 they are no way comfier than a ZS.
I kept mine for nearly 3 years and flogged it because of the rattles &squeaks (only had 40k on it) which plagued the car.
Great fun to drive but very poorly built.....its probably the only car I've sold and don't miss!
