1999 Mercedes-Benz CLK GTR Roadster
Only six were ever built — the car cost $1.5 million new, after all — but if you're going to own any of them, it might as well be the first. This 1999 Mercedes-Benz CLK GTR Roadster was the first example produced, and the only one to sport a black livery. It was owned by the company until the current owner took delivery in 2014, and has just 8km (around 5 miles) on the odometer, meaning it's practically new. It has an output of 650 hp, an F1-inspired sequential six-speed transmission with paddle shifters, and a jaw-dropping design that will look great whether you drive it on the road or keep it in your garage.
