As well as the seamless windows would also indicate a/c on these particular GO buses although seamless windows were not a requirement for a/c equipped buses, they seemed to be preferred for some agencies like Chicago and the Southern California RTD. To add to Dan's point, the a/c worked wonderfully on these buses, but on this day I took this photo of 1100 September 1, 1997 the a/c did break down on an exceptionally hot day. It was the only time I ever had been on a GO New Look with malfunctioning a/c and on that day it was brutal. It was also the first time I had ever opened a New Look roof vent as evidenced in the photo, requested by the exasperated operator as I was the tallest passenger on the bus. I say exasperated operator as he was getting a lot of flack from the overheated passengers.
