• 2020 Mercedes-AMG S63 Cabriolet by Brabus and Fostla

A unique look for a unique car

LISTEN 05:01

When you own a car like the Mercedes-AMG S 63 Cabriolet and you’re looking to get some aftermarket work done on it, one tuner might not be enough to give you your desired results. Take the case of this particular AMG S 63 Cabriolet that was on sale at German online car site Mobile.de. This AMG S 63 Cabriolet has been treated to aftermarket work, namely from famed Mercedes tuner Brabus and Fostla, and the result will invite plenty of stares on the road.

What’s so appealing about this Mercedes-AMG S 63 Cabriolet?

On its own, the Mercedes-AMG S 63 Cabriolet is already a sight to behold. It’s a massive car — it measures 198.8 inches long and 83 inches wide — so any visual modifications it receives will be immediately noticed.

On those fronts, Fostla took up the task of wrapping the AMG S 63 Cabriolet in a unique Olea Green wrap with chipping protection.

You don’t often see a Mercedes-AMG S 63 Cabriolet in this particular shade of green — the only green shade available in the model’s online simulator is “Emerald Green” — so it’s a welcome look for the high-performance convertible. It works well, too, when you combine it with blacked-out chrome trim and the set of 21-inch brass wheels that look more like wheels dressed in a matte gold finish. The color combination works well in giving the AMG S 63 Cabriolet a striking appearance.

Speaking of striking appearance, the overall look isn’t complete without mentioning the carbon fiber body kit that Brabus added to the big convertible. The kit includes the usual parts and panels, namely a new front apron, a rear diffuser, and a rear spoiler. Brabus badges are also part of the body kit.

From certain angles, it looks less like a Mercedes-AMG S 63 Cabriolet and more like a Maybach. That’s a compliment to the two tuners responsible for the vehicle’s makeover.

Is there an engine upgrade for this particular Mercedes-AMG S 63 Cabriolet?

No, there isn’t one, but that’s not at all surprising since this is a customer-owned AMG S 63 S Cabriolet. This is a good example of a vehicle with a Brabus aerodynamic kit that doesn’t carry an engine upgrade. Instead, the AMG S 63 Cabriolet carries the same 5.5-liter twin-turbo V-8 engine as its standard model counterparts. The unit still produces 577 horsepower and 664 pound-feet of torque so you’re not necessarily grasping for power here.

In standard form, the AMG S 63 Cabriolet can still accelerate from 0 to 60 mph in just four seconds on its way to an electronically limited top speed of 155 mph.

How much does this specific vehicle cost?

Back when it was still listed on Mobile.de, this car came with a buy-it-now price of €148,000, including taxes. That converts to almost $175,000 based on current exchange rates.

For comparison’s sake, a brand-new Mercedes-AMG S 63 S Cabriolet starts at $183,500. The price difference isn’t that big for a model that already has 13,670 miles (22,000 km) on its odometer. Remember, though, that the listed price already includes taxes and there’s also a premium added when the model carries aftermarket work from Brabus and Fostla.

Without these modifications, 2017 to 2018 AMG S 63 Cabriolet models with similar mileage on the odometer costs anywhere from $95,000 to $110,000.

Final Thoughts

On face value, this Mercedes-AMG S 63 Cabriolet is expensive. Even with taxes included, it shouldn’t cost $175,000. That’s almost the price of a brand-new 2019 Mercedes-AMG S 63 Cabriolet. On the other hand, the uniqueness of this particular model with the Fostla wraps and the Brabus carbon fiber body kit adds a splash of exclusivity that you won’t get from a standard AMG S 63 Cabriolet.

I personally wouldn’t buy this car at the posted price, but it appears that with the listing now off the board, someone has already scooped it up.

  • Leave it
    • Expensive for a car with almost 14,000 miles of run
    • No engine upgrades
    • Looks to already be sold

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
