I got a building kit of the bus KAROSA B-931 as a christmas present. I didn’t make the best model bus, because it was my first building kit.
Kit is from SDV company but it is not very detailed and nice. It needs to add more details after made it. I try it on my model. You can see in photos below. I highlight text KAROSA and logo K. I put some people into bus, too. For example, you can see bus driver. Now, I think that it can be better with lights.
