The Prevost X3's look good in the neo-livery, as do the D4505's, but I wont derail this thread anymore.

As far as for Jefferson Lines, I remembered something interesting. I was once riding home on Greyhound from Little Rock, and as I was transferring buses, a JL bus pulled up, and it was a Van Hool C2045. It was tan in color, and had the JL logo on it. This was back in 2002. They have updated their livery since then. but I remember that bus because I had never seen one like that before, and it just stuck in my head.
