Chrysler today announced a new incentive program dubbed ‘Double CA$H for Your Old Car’ that can save consumers up to $9,000 toward the purchase of a new Chrysler, Jeep or Dodge vehicle. Under the program, everyone shopping for a new car or truck qualifies for an incentive of up to $4,500 – even if they don’t have a vehicle that qualifies under the U.S. government’s own scrappage scheme.

Starting on July 23, Chrysler will offer up to $4,500 in cash or 0% financing for 72 months through GMAC Financial Services on most 2009 model vehicles.

Coinciding with the launch of the new incentive program is the start of the U.S. government’s Car Allowance Rebate Systems (CARS) scheme, more commonly known as ‘cash for clunkers’. The CARS program offers a government credit of either $3,500 or $4,500 for trading in an inefficient vehicle that is not more than 25 years old for the purchase of a new vehicle. The amount of the credit is determined based on the fuel-economy improvement between the turn-in vehicle and the new vehicle purchased.

Chrysler’s new incentive program will run right up until August 31.
