General Motors has made a habit of offering first production cars of various nameplates for charity. Recent notable auctions saw cars such as the 2015 Chevrolet Corvette Z06 and the 2014 Camaro Z/28 raise money for charity, and the 2015 COPO Camaro is set to go under the hammer to benefit the needy as well. Now, GM has just announced that the first 2016 Cadillac CT6 to roll off the assembly line is also headed to the auction block. The innovative full-size sedan will raise money for the Karmanos Cancer Institute, a research center dedicated to the prevention, early detection, treatment, and eventual eradication of cancer. It will be auctioned off at the Barrett-Jackson Collector Car Auction in Palm Beach, scheduled April 17th to 19th.
