Very often in the paris airport terminals or railway stations, limousine drivers approach travellers and offer a ride cheaper than taxi, which is not true and depending to the company, their service usually cost much more expensive than taxi. They have no taximeter and they make their own fare price ! For tourists is not easy to compare quickly those limousine prices with taxi fares, so they often take advantage of uninformed visitors.
These limousines often are just the private cars, they don't have taxi sign & logo, neither the registration number, and sometimes they are illegal workers.
According to France Laws, approaching the travellers in airport terminal, railway stations or any other places and offering them a ride is illegal and people doing this can be prosecuted.
Remember; Official taxis never approach travellers to offer their service in train stations or airports etc !
Always take un official taxi, which has the taxi sign on top of the car roof and has a taximeter on the front dashboard, visible to passengers.
