I drove the 118i with the new automatic gearbox (8 gears) and I didn't like it
At start, the car always did a forward jump of about 5 meters and it needed a lot of benzine (only in the economic mode, it may be possible to drop down consumption near official value but then, the engine has no power!)
The internal room space is mutch under what the civic proposes.
About road noise, it is very silent and the confort is good too. Both are very closed together.
About the price! (many extras have to be added to get near what the civic has. To compare (in euro), the new civic exclusive cost about 27800€ including automatic gearbox. The BMW Serie 1 with the same options cost near 38000€ !
