My friend started driving one of these in NY about 15 years ago. I don't recall the exact figures but he quickly realized renting a $1000 vehicle for $60 a shift made no sense so he bought one and paid it off in two weeks or so. Within a few months, he had a fleet of ten and a full time manager running them, while he pocketed about $300 a day. Back then, there was no regulation. Today there is more, registration and insurance plus driver background checks but he still lives a pretty good lifestyle. They used to be a cheaper alternative to a yellow cab, now they are much more than a taxi.
