If would give it an try.
So its +-1, cause yes, it would be fun to have more than just the skoda car in game, but 1. it would cause so many players drive with the cars and 2. the cars look ugly and have bad textures, with no interior, wich makes it even worse, to add all these into the cars.
Like @happy_trucking_ets2 said, we can give it a try and bring the cars in for a certain amout of time.
I would like it much more if they would add some variety to the skoda, like some new trailers or remake the engine sounds.
