If I were you, and you can get hold of it for that price, I'd just go for it and not worry about putting passenger seats in. You can always fit benches (if it doesn't have them already). Forget the doors, it'll cost you well over £500 in parts including fixtures and fittings alone. Door pillars and the like aren't cheap, especially if you buy them new. You've got a door at the back which should be perfectly sufficient. I don't know about the legalities of how many doors you need for a soo many seater vehicle, but a coach only technically has one or two doors (and at least one emergency door). You'd have three! If they want their own private door, tell them to feck orf, they should be happy to have the privilege of traveling in such comfort and style
