MOBILE, Ala. – GMAC Financial Services' debut as a college football bowl title sponsor got off to a sizzling start Wednesday night. Southern Mississippi scored a touchdown in the final minutes to break a tie to defeat Texas Christian, 28-21. GMAC Communications chief Jim Farmer and Mobile Mayor Mike Dow shared coin-toss honors to get the contest started. Also on hand were GMAC Vice Presidents Keith Constantine, Southeast Operations, and Jim Kobus, Residential Mortgage. And one lucky fan, courtesy of GMAC, took home $1,000 after tossing a football into the hatchback of a Pontiac Aztek during halftime celebrations.
