Just over a week ago, we saw the long-roof Mercedes C-Class on a winter adventure, dropping some of its swirly camouflage wraps in the process. There were two prototypes seen before, one likely showing an upper-spec model.

Our spy photographers have spotted the C-Class estate again, but this time near the Mercedes-Benz headquarters in Stuttgart. Plus, it looks like a trim in between the two prototypes we've seen before.

That conclusion came from the fact that this prototype comes without a sunroof but it has tinted rear windows and black side mirror caps. It also has a set of similarly-sized wheels with the top-spec trim we've seen before, plus similar embellishments concealed within the wraps.

As for the lighting, the C-Class estate seems to have adopted the configuration from the larger facelifted E-Class. The changes are more evolutionary than revolutionary – enough to give the compact car a more modern look than the outgoing model.

The C-Class estate may be the subject of rigorous testing these days, but we all know that the C-Class saloon goes parallel to this development. More importantly, we know that the C-Class saloon is all geared up for a world debut later this year, giving birth to the W206 model.

The estate, or the T-Modell in Germany, will have to wait a number of months before its global reveal. The hotter AMG C-Class models will be launched further in 2022, along with the believed All-Terrain version of the C-Class.
