GMAC 1 YR CD 5.00% APY

I've noticed that GMAC rates has gone up again. Its now at 4.88 APR/5.00 APY. They are aggressively increasing the rates to attract investments, good thing that the account is FDIC insured especially its mothership GM is burning cash like it is an internet portal. GM is trying to sell its controlling stake in GMAC to make some change (in the range of 10-15 billion).
