The manufacturer is offering zero percent financing for up to 72 months through GMAC Financial Services or up to $4,500 cash back on select 2009 model year Chrysler, Jeep and Dodge vehicles.

In addition, Chrysler is offering $2,000 cash back or special financing rates through GMAC on select 2010 model year Chrysler, Jeep and Dodge vehicles.
