"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
Fly and rent a car when you get there is probably cost effective when the destination is over a thousand miles away.
Goldie you must live in a bunker, 600 miles is nothing. Consider, New England to FL for the retirees, road warriors [salesmen]and beyond.
You lost me on that one. Doesn't sound like you are factoring in the price of YOU getting to where the car is. And what if you are a family of four? According to what you posted it would be cheaper to have my car transported 600 miles and for me and my family of four to fly there than to just get in the car and go.
You must have meant something else.
