Who did that to those poor cars? N°2 - Solved by ImpishGrin, Neilshouse, K5ING, Allemano, Arunas and Ehhxekt

[Allemano]

"Franck's Genuine Coffee Supplement" (Franckovka) is the product you're waiting for? Other products names were "Karo Franck" and "Perola" Rye coffee.
Kavoviny continued the old Franck's tradition since 1991. I've to admit I didn't read the whole story before. 
"Karo Kaffee" was the hot drink of my childhood.. 

And yes, meanwhile I recognized the "English" button.

It's really amazing that while putting this puzzle together I've stumbled upon a brand who precisely made the drink of your chiidhood! Were you living in the D.D.R., or was the brand also sol across the iron curtain?
As I understand, the name Kavoviny wasn't in use until after WWII. That's why I didn't accept your first answer. Now I think that this last car was difficult enough to earn you 2 points.

Thanks to Allemano for having allowed us to finally solve this group puzzle.
Now you may notice that several of the cars here were to be found in a particular category of a certain website.... Now there is another "Who did that..."

[Allemano]

Guess "Caro" coffee was more like a synonym for products of different brands (Nestlé today).
Maybe the brand name wasn't protected or was sold ages ago.

I'd never set a food on the eastern territories before 1993...
