Boot space is 350 litres with the roof up. An electric partition allows the soft top to stow while leaving usable space for luggage when the top is down.
AMG models use adaptive sport suspension based on AIRMATIC as standard. No towing capacities are published for the Cabriolet. Payload is listed around 450 kg depending on variant. This is a luxury open-top car with limited practical work use.

ASSYST PLUS monitors conditions for Service A/B intervals, typically around 10,000 miles or one year.
Standard safety includes PRE-SAFE, Collision Prevention Assist Plus, multiple airbags and pop-up roll bars.
AMG models often include Driving Assistance package elements as standard.
AMG models use premium fuel and return economy in the mid-teens to low-20s mpg range depending on engine and conditions. Larger V8 and V12 engines increase consumption on the open road or with spirited driving. A sizable fuel tank supports longer trips between fills.
Servicing follows the ASSYST PLUS system that adapts intervals to actual use rather than fixed mileage alone. Service A and B alternate and cover oil, filters, fluids and inspections. Expect dealer visits roughly yearly or every 10,000 miles under typical conditions.
Safety equipment centers on PRE-SAFE preparation, radar-based collision prevention, stability systems and a reinforced structure with deployable roll bars. Multiple airbags protect occupants. Optional or package driving assistance adds adaptive cruise, lane keeping and blind-spot features. The cabriolet was not separately crash-rated in major tests.
Ownership means caring for high-quality materials, the multi-layer soft top and complex electronics. Regular ASSYST services and attention to the top mechanism help preserve the car. Tyres, brakes and consumables wear faster on a heavy performance convertible.
