How do I tell what options a bus has?

It won't tell you everything, but I've found THIS PAGE to be accurate as far as it goes. It only covers Blue Bird buses, but since those are the ones you're interested in, it should be helpful.

Thank you for that much needed information.

2 g's seem to be a good deal for that bus assuming it runs and drives good. it may even have 5.9 cummins and mt643 if your lucky.
