Excellent 3D model, well detailed, but something still "hurts" me, the weight of the bus. Looks like I drive a very light weight bus (< 1 ton). Hope you can fix that, but V3D is always a good value!
By the way, I'll disable the indicator sound, I know it's not your fault, but, the engineer who thinks this indicator sound is great should be fired. That strident sound all day long, he's just crazy.
