Hey GM !
How about bumping up the $500/yr ceiling on the original GM Card? The card started (in 1994?) with a $1000/yr ceiling with 7 years of accrual for a $7000 cap. Then, somewhere around 1998, you cut the program back to $500/yr, 7 years, $3500 cap. Well, it's been 15 years now and the cost of everything has gone up (including the cars), making this benefit less and less valuable. As a percentage of GM Card holders, there can't be many people left in this program after many of them "switched over to" the "New" GM Card (in '98). Why not reward these loyal customers with a ceiling bump (say, to $750)? It wouldn't be without benefit to you. Many of these people probably stop using the card once they reach the maximum accrual for the year. You'd get another $5000 worth of charges (i.e. merchant fees) from every one of these card holders in exchange for $1750 more in rebate dollars at time of car purchase. Sounds like a win-win to me.
