Just like the non-facelifted 1-Series hatchback and pretty much all the other BMW models manufactured since 2004 or so, our 120i Cabriolet was equipped in standard with run-flat tires and no spare tire, thus making room for the car's battery to reside under the luggage compartment. Technically this means two a bit antithetic things.
First of all, the car's dynamics are very close to a real sports car, since the axle weight ratio is close if not even identical to a 50:50 distribution. Second of all, because of the same reasons the car is stiffer than you would expect from a leisure convertible that won't be used to break any records on the Nordschleife.
Apart from the aforementioned, the car's suspension is closer to "rigid" than to "cushy" on the comfort scale. Don't get us wrong, the suspension setup won't give you back pains on a daily basis but the fact remains, even in 120i trim, the 1-Series is still very close to a sports car. Apart from the obvious throttle and steering wheel, the onboard "pleasure givers" were pretty much kept to a minimum on our test car.
It had a dual-zone climate control system which works pretty well regardless of the position of the roof as long as the windows and/or the wind blocker are up, a BMW Professional audio system and that's pretty much it. The seats were manually adjustable except for a very interesting feature. That was the electrically adjustable side bolster support for both front seats, which technically changes the seats' shape around you just by pressing a button. Therefore, they can accommodate almost anything, from the thinnest guy/gal out there to a pretty large person.
Other than that, there's the leather upholstery on the seats, which didn't quite blow us away with its look and/or feel. Maybe it was because it was UV treated or something, but it wasn't exactly as soft as a baby's bottom.
