Welcome, Sparkey. I have a 1.2 S which I have had for the past three years. It is a great little car, with 113,000 miles on the clock, almost 30,000 of which I have done. The figure below my avatar is the average mpg during my ownership, and at the moment is sitting at 54.2 mpg. I just get in, turn the key, and it goes. I am over 6 foot tall and find it very roomy, except when my wife tries to reach back between the seats when I am reaching for the handbrake!
A thing about the handbrake. It operates on the rear discs, and is often described as inadequate. The dealer who sold me the car is an ex Honda mechanic, and he told me to firmly apply the footbrake then pull up the handbrake. I have never had the least worries, even on the steepest hills.
Be aware that the DSi engine has 8 spark plugs, 4 along the front and 4 along the back. Many independent garages (and even some Honda mechanics) are unaware of this.
