Forget the SLR, SL65 Black and SLS Gullwing - the Mercedes CLK GTR is the most outrageous car ever built by the German car maker.
And now two of these road-legal race cars are going under the hammer at a London auction next month including a super-rare Roadster.
According to RM Auctions - which is organising the auction in Battersea - just 25 CLK GTRs were built including five Roadster models. Both models are the only right-hand drive variants ever built.
As the pictures show, the CLK GTR is bonkers. Wide, low and long, Mercedes fitted the CLK GTR with a 7-litre V12 located behind the driver and passenger.
The normally-aspirated engine develops 612bhp and enables 0-62mph in 3.4 seconds and a top speed of 200mph.
Race-car features include a six-speed sequential gearbox with paddle shifts, independent front and rear suspension with double wishbones, pushrod-actuated coil springs and shock absorbers, and four-wheel ventilated, anti-lock carbon-fibre disc brakes.
These models belong to a 'prominent car collector' with rumours suggesting it's the Sultan of Brunei. Both cars have done less than 30 miles - which is a travesty.
RM Auctions have given the Coupe a list price of between £370,000 and £390,000 while the rarer Roadster is commanding a premium of between £430,000 and £500,000 - considerably cheaper than the £1 million-plus they cost the buyer new.
