Our local school district has an '83 Blue Bird flat nose for sale. From what I'm told, it's an 81 passenger bus with a Cat 3208 paired to an Allison MT643, with under 200K miles.
I've seen the outside several times, and it looks really nice, really clean. I believe they want somewhere around $4000 for it. If anyone is interested, contact me and I'll put you in touch with the right people, and if you want pics, I'll post some.
