"barmcd".....His procedure for doing the purchase is the way to go. Get a deposit down so you don't lose the coach and then get the inspection done. You can then negotiate any repair into the price.
Even though you might have it inspected, I would definitely look do your own detailed inspection. You can have mechanical items inspected, while you look at how it was cared for, like paint, interior carpeting, furniture, etc.
