An Executive car service is something that is very regulated by either a company or a corporation. In an executive car service company, all the vehicles are owned and insured by the company and all drivers work for that company. This allows said company to exercise control over it’s employees, it’s vehicles and it’s services.
This is really the major difference. An executive car service will have new cars; they will be clean and properly maintained both ascetically and mechanically. Their chauffeurs (chauffeurs not drivers) will be properly and uniformly attired, usually in a black suit or tuxedo. Dispatch and reservations will be consistent, organized, and professional. This is how a true executive car service is typically operated.
