Safety
Active head restraints, two-row side curtain airbags, front airbags and side-impact airbags for the front seats are all standard. So is an electronic stability system, antilock brakes and traction control. Like most convertibles, the 128i convertible does not have the curtain airbags; it does have pop-up roll bars behind the rear seats that deploy in the event of a rollover.
