This is the Mercedes SLR 722 GT, and it redefines the meaning of the word ‘rare’.
This probably explains why there aren’t any available on the market.
And when one appears, usually only once every few years, it ends up selling for well over $1 million.

The Mercedes SLR 722 GT is a rare iteration of a special-edition variant of a car that’s already far from common.
The Mercedes SLR McLaren was launched in 2003 and a few years later, in 2007, Mercedes unveiled the SLR 722, a tribute to Formula One driver Sir Stirling Moss.
In 2007, they went one step further and made a GT version of the SLR 722.

It’s powered by the same supercharged 5.4-liter V8 as the ‘standard’ model but this one produces 671 horsepower, nearly 60 more than the original.
And this car is lighter, too, tipping the scales at just 1,390 kg, which is a whopping 398 kg lighter than the road-going version on which is based.

After these mods, the SLR 722 GT is capable of reaching a top speed of 196 mph (315 km/h), and it does 0-60 mph (0-97 km/h) in just 3.3 seconds.
The only downside is you can only use this car around a track because, as you can see from the barren interior, this is a track-only car.


Only 21 units were produced and it is nigh on impossible to find one for sale.
And there are two reasons for that.
First, one of these cars – the orange one you see here – is a permanent resident at the Motorworld Munich Museum in Munich, Germany.


So that means that, at best and assuming all the other cars are still in one piece, there are only 20 units in the hands of private collectors.
And the 20 collectors that bought one just don’t want to part ways with them.
And to be honest, we can’t really blame them either – can we.
