I tested it and it does quite good, I would prefer the CVT but at a price difference of 2000 euro I get the manual one. The reason i didn't take the 1.2 manual is that I still have to pay tax when I get 1.2 manual, 1.0L manual is tax free until january 2014, so am not paying tax for the car at this moment.
It's performance does depends on the number of people sitting in the car, I had the car fully loaded with 5 persons today and immediately you notice the suspension's not sufficient, at the first road bump it the car hits the bottom and it's utterly inconvenient for the rear passengers. It's something Mitsubishi does though, my Galant's all the same although in the Galant you sit very comfortably.
