As a seller I have to say when people start talking about escrow services, held checks, or my favorite, joint bank accounts I get nervous. Buying a car is very simple, you pay for the car, the car ships. Amazon doesn't send you a laptop until they are paid, nor should they, and nor should someone selling a car. If you are nervous about doing a remote deal on a car then get on a plane and seal the deal in person, or if you don't have time to do that then I suggest you make a list of car dealers within 100 miles of you and give them your wish list for a car.
In this day and age simpler is better, always.
