It lines up as a direct rival to the Bentley Continental GT convertible, which also is powered by a V8, starting from $504,700, before on-road costs. 

It will also be an alternative to the electric-powered Rolls-Royce Spectre, starting from $800,000 (before on-roads). 

The SL680’s 4.0-litre V8 produces 430kW and 800Nm, which is more than the Continental GT.

The car comes as standard with an all-wheel drive system and is capable of completing the 0-100km/h sprint in 4.1 seconds. 

It gets a sweeping exterior design, and with 50 paint choices, as well as 21-inch wheels in two options, the second of which is a multi-spoke design costing $12,900.

It has polished interior elements, including silver chrome trim and illuminated door sills, along with a wood and leather steering wheel. 

There are Napper leather seats, which are heated and ventilated, as well as a premium 17-speaker Burmester audio system, which can output 1220 watts. 

It also gets all the accessories you would expect as standard like wireless Apple CarPlay and Android Auto connectivity and wireless phone charging. It also features Mercedes’ augmented reality navigation system.

As you would expect, this high-end Mercedes has some seriously pricey options aside from the aforementioned wheels.

For $16,900, the car can be fitted with a Mercedes-Maybach pattern on the bonnet and for an extra $24,300 the whole car can be finished in an exclusive paint. 

The SL680 adds to the Mercedes Maybach range, which already includes versions of the S-Class limousine, as well as the EQS and GLS SUVs.
