VTA busses are so dirty compared to Sam Trans busses both inside and out. As I driver myself, I've had more than one passenger tell me this, so I checked it out. It's true. When I pulled in one night I noted that in 25 min. my bus was "cleaned", oil checked, gassed and put thru the wash and in the pullout format for the next day. 25 minutes done.
I did a walk thru on a Sam Trans bus myself.
The difference was night and day.
