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 135i convertible does not have the curtain airbags; pop-up roll bars deploy behind the rear seats in the event of a rollover.
