I have used Tel Aviv Limo on several trips to JFK and one to EWR. They have almost always been "on time" (You have to call the 800# upon arrival and they are there in a few mins). The fees are reasonable. The cars/vans are variable, from mediocre to very nice. The return to the airport, the car usually arrives early. I'd give them a A- for the dependability and a B for the rest.
