The big problem comes when those vehicles don't sell, and the factories have to be shut down.

The vehicles sold extremely well and spread all over the world.

In 2007, the average new vehicle sold for about $28,000.

By the end of the year, the 2004 vehicles were selling with significant discounts.

The vehicle will sell for a base price of $84,000.

The vehicle sold for $300; the charity got $5.

But with gas prices around $3 a gallon, how well those vehicles will sell is in doubt.

But guess what vehicle has sold best so far this year in Southern California?

In August, the best month so far this year, vehicles sold at an annual rate of 15.7 million.

Car makers can cut production when vehicles do not sell.
