Limited to just 300 units globally, the Maybach S650 Cabriolet is touted as "the ultimate in open-air exclusivity", priced from 300,000 euros ($427,451).
Like the Maybach S600 limousine before it, the S650 features high-end exterior and interior appointments over its lesser siblings, along with a twin-turbocharged 6.0-litre V12 engine under the bonnet borrowed from the heavyweight AMG S65.
Despite being pitched as an uber-luxe offering, the S650 produces a mighty 463kW of power and 1000Nm of torque.
Sent to the rear wheels via a seven-speed automatic transmission, the plush drop-top can power from 0-100km/h in a claimed 4.1 seconds on its way to an electronically-limited top speed of 250km/h - not bad for a land yacht.
Distinguishing the Maybach S650 from more 'pedestrian' S-Class Cabriolet models is a new front bumper, lashings of chrome just about everywhere, Maybach badging, 20-inch Maybach forged alloy wheels in 'bi-chromatic' finish, along with puddle lamps that proudly display the Maybach logo when you open the doors.
Inside, the exclusive theme continues with a full-leather trimmed interior, a waterfall-like pattern in the seat perforations, and diamond quilting in the seat side bolsters.
The trim elements of each vehicle are specially commissioned based on the colour and grain. Exclusive to the Maybach Cabriolet is the nut brown magnolia trim from the company's designo line, along with a special trim on top of the soft top compartment that is branded with an inlaid Maybach logo.
Nine interior colour concepts are also available for further individualisation, including pastel yellow/black to porcelain/saddle brown.
The Maybach logo also adorns the front side of the seats, on the back of the head restraints and also inlaid in the cover of the centre console.
Each vehicle also features chrome-plated "1 of 300" lettering on the cupholder, while the lower bezel of the steering wheel is branded with Maybach lettering.
Other features included as standard equipment that are optional on other S-Class Cabriolet models include the Aircap wind deflector, Airscarf neck-level heaters, and Swarovski crystal headlights.
Buyers with enough cash to splash on one of these land yachts will also receive an exclusive Maybach luggage set, a diamond-quilted fabric car cover with an embroidered Maybach logo, along with a nappa leather keyring that matches the vehicle's interior colour.
A spokesperson from Mercedes-Benz's local arm has confirmed that a handful of Maybach S650 vehicles will make it to Australia, though the company isn't expect an allocation of more than 10 units.
Local pricing is still to be confirmed, but expect the uber-luxe drop tops to cost a pretty penny.
As a guide, the Mercedes-Maybach S600 limousine starts at $449,000 plus on-road costs, $30,000 more than the equivalent S600 L.
Meanwhile, the current cream of the S-Class crop, the AMG S65 Cabriolet, kicks off at $522,000 before on-roads, meaning the Maybach edition could creep towards the $600,000 mark, potentially more.
