Based on the Forbes 2005 report I have listed the ten most expensive cars available in the United States.The 2005 Salen S7 with a price tag of $560, 000 was the most expensive at the times of this report. Many of the more expensive cars in the world range from $351,000 upward depending on many factors: Luxury, Sport, Economy and where it is made and sold.
