2012 Jeep Grand Cherokee SRT8

The new Jeep Grand Cherokee and Dodge Duragno do wonders for the Chrysler Group LLC. So much so that the company's Jefferson North plant decided to remain open through the normal 2-week summer shutdown. Most automakers close factories in the 4th Weeks of July to make cars for the new model year and machine maintenance work form.

However, spokeswoman Jodi Tinson said Chrysler, the plant that makes the Grand Cherokee and Durango will remain open through the summer. In the first quarter of 2012, sold 38 000 units of the Jeep Grand Cherokee - an increase of 44 percent. Dodge sold 11,000 units - an increase of 33 percent.
