I can't really even describe how it feels when you ride one of these "buses"...
The noise and vibration is just so horrible and I think there is no other bus that beats this in vibration. Engine has four cylinders but it feels and sounds like a lawnmower engine that has only one cylinder... The semi-automatic transmission also isn't a good choice for a bus like this. They are designed for long-range coaches and trucks.
