Even though GMAC spun off from GM years ago, they recently changed their name to "Ally" in a re-branding, stain-of-association-removing effort. Their whole game seems to be a USAA for civilians, advertising "No minimum deposits. No fees. No min balance. No sneaky discalimers." Ally Bank is also offering very juicy APYs, like 2.25% for an online savings account, more than double the national average...

One unique product they have is a no penalty for early withdrawal 9-month CD at 2.5%. Bargaineering gives them a thumbs up. And they must be doing something right, because the American Bankers Association - the same guys who protested the CARD act - sent them a letter (PDF) saying "pretty please don't offer consumers such high interest rates it's not fair to actually have competition." (Ally Bank's rebuttal (PDF) also makes for a fun read).
