I propose a curious bus: BredaMenarinibus Monocar 221.
It was produced between 1997 and 1999, and today many companies still use them on regular service.

This bus is almost 23 years old, but howewer it's still reiable.
A quality of this bus is that the driver has good visibility in the front of the vehicle, thanks to the raised position of the driver and the large windshield
It has a nice ZF gearbox too!
If you want, here there is also a "ride-video" into the bus in the picture above:
