Speaking of pet peeves with certain express bus models..As a tall person, the old MCI Classic express buses kinda sucked, I hit my head on the reading lights/luggage rack when I was on 3006 at busfest many years ago. Most of my MCI Classic rides were the transit seat versions that Green Lines had, which didn't have reading lights, etc, so headroom wasn't an issue. By the time I started fanning express buses the MCI Classics were long gone sadly, I sadly cause their powertrain was pretty cool.
I rode the BXM8 not too long ago on a warm summer day and there was NO air coming out of the damn vents, the coldest MCI I had been was a old 1800 out of SC.
