Previous spy photos have shown prototype vehicles with their tops up, but also with a layer of camouflage and disguise on top.
A few pieces of strategically placed false panelling and the odd straight line have led someone online to wonder if the upcoming C-Class convertible will go head-to-head with BMW 4 Series convertible in offering a electrically folding hardtop.
These latest photos show that the new C-Class convertible, the first of its name, will indeed feature fabric top.
Under the skin, the convertible will share most of its components with recently launched C-Class coupe. In the interests of structural rigidity there will likely be a few extra structural elements hidden away below the surface.
Naturally the roof mechanism and bracing will cause the cabrio to be heftier than its fixed roof counterpart, but performance shouldn't differ too much, at least at speeds that are legal in Australia.
Drivetrains options will be roughly line-ball with what's offered in the coupe. Engine options in the coupe stretch from the 115kW 1.6-litre turbocharged four-cylinder in the C180 all the way through to the 375kW/700Nm twin-turbo 4.0-litre V8 in the AMG C63 S.
This C-Class convertible prototype was spotted in a Mercedes-Benz holding yard. In the background there's a GLC Coupe prototype, while the foreground there are a number of next-generation E-Class sedans.
