I would call these guys scam artists, but that title implies that some craft or effort is put into their scheming. These guys are just hucksters, who will manipulate Expedia or whatever to show you a price nowhere near what you will end up paying.
Hidden charges, lying to your face about provincial requirements, mediocre cars. The works. That some people go to jail for, say, simple drug possession and that these guys have been allowed to stay open is concrete proof that the everyman is under the bootheel of the courts and businesses and you can get away with anything so long as you're incorporated.
