The M1 looks like a 3 Coupé washed too hot. IMO, this is a really unattractive design. A compact car should not pretend to be a "grown-up". The Clio, ont he other hand, is just a power egg, and designed like a power-egg. I love this kind of car. Small, agile, low weight, much power. But fully capable as everyday transporter, with manageable service costs.
The only thing I really like with the M1 is its colour.
