The Mylon Le Fevre coach ended up at I-44 Bus Sales in Sarcoxie, MO, where it sat for almost two years. That bus almost became Odyssey -- we looked at it early on, even had it driven to Lamar for a full inspection. Ultimately, we passed it over, since it had several problems and we would have had to do quite a bit of body modification to get the motorcycles into it.
The air-operated side entry door is a standard feature of Spaceliners -- not somethinng Mylon had done to it.
With regard to lowering the floor on the Cityliner, you should be aware that this coach is a monococque design, and the floor truss is an integral part of the load-bearing structure. Moving it means doing, among other things, thrust analysis and calculations. Also be aware that the sides of the aisleway are major structural elements. Not saying it can't be done -- my coach has a lowered floor from the factory in Pilsting. Just that you need to do the engineering first.
