Colorado new vehicle sales in October were up 31.6 percent when compared to the previous October.

According to the Colorado Automobile Dealers Association, year-to-date vehicle sales are up 22.9 percent in Colorado compared to 2011.

The number of cars registered increased by 26.1 percent year-to-date, while the number of pickups increased by 20.5 percent.

Nationwide, vehicle sales are up 13.3 percent year-to-date, according to the association.

"This postive trend has been consistent for several months in Colorado," said Tim Jackson, president of the Colorado Automotive Dealers Association.

"I think historically low interest rates, easier access to credit, more diversity in brands and features and demand for fuel-efficient models are all factors which combine for healthy vehicle sales throughout the state," Jackson said.
