[OSM-newbies] Any tag available for a bus hire company?

[Sebastian Arcus]

There is a local company which does bus hire. For example double-decker 
buses (with drivers) for weddings and other occasions. I can't figure 
out what should they be tagged as. I don't think amenity=car_hire would 
come even close to their scope of activity. Is there some other type of 
vehicle hire tag - or similar that could be used instead? Surely these 
places/companies exist in other places around UK (and other countries, I 
guess)? Maybe I should at least tag their premises with the proposed tag 
landuse=depot?
