I kinda like the idea of a letter grade if lenders would say things like Super Prime would be the best rate. I noticed the when I was in New York for Thanksgiving, there was a big range diffrence in the FICO score that some auto dealers were using to get their best deal. I saw scores like 720, 740, and 760.
