I booked on the phone with a person on a Tuesday night for a 5 am Thursday morning run from Manhattan to JFK. When I called at 5am to ask where my car was, they said, whoops, sorry, it'll take 20 to 30 minutes to send a car to you. They didn't call to alert me, they didn't even seem to know about my appointment until I called them! LOUSY LOUSY SERVICE. I cancelled and grabbed a cab which cost less than their service would have. If you need a car service, call anybody but these guys.
Cons: don't show when you have an appointment.
