You don't have to worry about whether it's safe to put your kids in this convertible. When driving with the top down, the C70 has roll bars that pop up behind the rear seats if the C70 tilts past a certain angle, providing protection for you and your passengers in the event of a rollover crash. The C70 also has been crash-tested by the Insurance Institute for Highway Safety. It received the top score of Good in front, side-impact and rear crash tests. It hasn't undergone IIHS' latest crash test that determines a vehicle's roof strength.

In addition to the roll bars, the C70 has standard four-wheel-disc antilock brakes with brake assist, traction control, an electronic stability system and six airbags, including seat-mounted side-impact airbags and side curtains, both for first-row passengers only. The C70 also has a Whiplash Protection System.

While there are plenty of features to keep everyone safe in this midsize convertible, there isn't a lot of space in the backseat for child-safety seats. A rear-facing convertible or infant-safety seat is out of the question despite the presence of lower Latch anchors. The C70 doesn't have tether anchors, which isn't unusual in convertibles. A forward-facing convertible will fit in this car, but you have to decide if you're willing to go without using the all-important tether strap. Booster seats fit OK in the backseat, but they'll fit better if the booster is narrow. Interestingly, the seat belt straps are on the inside of the rear seat, and the receptors are on the outboard side of the rear seats. This was just a little different but no cause for alarm.
