I have no connection or association with these:-

There is only one of these Charabancs in the UK which is licenced to carry passengers.

Not so sure that you would be able to drive it though . . .

Bedfords (Isle of Wight based):- http://www.vintage-tours.co.uk/page26.htm

Wales:- http://silverstarvintagecoach.com/

East Anglia:- http://www.carterscoachservices.co.uk/

Not sure if any of the above allow you to drive the vehicles yourself.
