I've been driving this car for over one year, so I think I'm qualified enough to evaluate it.
First of all, I think it's a pretty decent little car with low running costs. The car's performance is satisfactory considering it has a tiny engine.
Handling is better than I thought. The car rides very smooth on highway. Shock absorbers work nice on bumpy roads. Stability at high speeds is very satisfactory. The top speed I reached was 140 mph and the car was still stable. Car doesn't take much noise inside the cabin, until you hit 80 mph.
The trunk capacity is far from small for a super mini.
Safety stats were a big buying point for me.
Fuel economy is phenomenal for a gasoline car. I get about 35 MPG in city and 45-50 highway..
I like the design of the car. Being an aerospace engineer, I consider myself meticulous about the car's design, largely about aerodynamic performance, drag coefficients etc. But I think Renault designers did a really nice work on Clio's front end design.
Despite the car being considered overall good, it still has some negative points: There's no sign of comfort in the back seats. Long uphills become a pain shortly; a 1.2 liter engine is no good for mountain climbs.
Although it has a few drawbacks, I like this car and am completely satisfied with it.
