Yes, it's silver.
The Mercedes-Benz 300 SL is considered by many to be the very first supercar, and if that's the case, then the 300 SL Roadster must therefore be the first convertible supercar. Though it is the hardtop with its gullwing doors that springs to mind first when we think of the classic, Mercedes actually built more of the Roadster - by a few hundred units anyway. Both are quite rare and total production for both body styles combined was just over 3,200.
The car had its inline-six engine canted at a 45 degree angle to accommodate the low hood, and mechanical direct gasoline injection was used to circumvent the problems with getting a carburetor to work with this setup. It also made the engine twice as powerful as carburetated versions, a big plus for a supercar. A Roadster version of the car just popped up for sale in Antwerp, Belgium, complete with classic silver paint and the original radio. The asking price is 1,050,000 euros ($1.3 million) and we're sure that the owner will have no difficulty in getting every penny of it.
