I've seen only about 2 different busses similar to this one, but both have too many missing aspects, no horn, no blinkers, and other various somewhat essential things. This one however, not only has a massive variation of busses to choose from, it also has every working feature any motor vehicle should have and more! I'm extremely impressed with the fans and the working light indicators in the cabin. Well done my friend, well done.
i know this took you 2 years but are you planning on making a different model if so please do a modern day bluebird with the lights i know that there are other bluebirds on the mod page but none of them have the realistic lights like your does witch i love and they dont even look like blue birds so this is just a suggestion please consider this is what it looks like this is on blue birds website https://www.blue-bird.com/buses/vision/vision-gasoline-bus
it does have 2 stop signs on the side like the one you made
