Now that the weather has warmed up sufficiently to get some traction in the M5 I am really, really, really loving that car. I was a little afraid to drive it over the winter on the summer tires, but the last two weeks have opened my eyes to its capabilities. It's nice too that the M3 feels different enough to be a pleasant switch, especially with the top down (It hit 63F earlier this week and I got to convert for a bit).
