CHATTANOOGA, Tenn. -- Representatives of General Motors and Chrysler LLC announced the expansion of the "Invest In America" pilot discount purchase programs to credit union members, as it's now available to members of the nation's 7,900 credit unions.

GM's "Credit Union Member Discount Program" extends to March 31, 2009, and Chrysler's "Credit Union Member Cash" rebate program extends through June 30, 2009.

With a certificate and proof of membership, a credit union member can receive a discount of 4.5% off the MSRP in addition to other available discounts on most General Motors products. With proof of credit union financing, a member can receive a rebate of $500 to $1,000 as specified for most vehicles from Chrysler (dealer participation is optional).
