Well, growing up as an 90s baby in Brooklyn, if you was into the bus side of this hobby you had no choice but to like the RTS as that's all BK had until JG got C40s, I still remember being excited about orginal C40s when they debuted.
JG had about 30 or so Orion Vs since the mid 90s until 2010 or so but they was VERY rare, I never saw one in my elementary years back then.
The only other bus I remember seeing was MCI classics on the BM's. If you didn't live along a Command bus express route then you never saw them.
