Wow... I had wanted a BMW for years, and finally pulled the trigger on a 525i CPO. I didn't see the need for the 530, as I believe the 215 HP on the 525 was enough. Amazing handling, feel, and I love the iDrive. I understand the griping, but all it takes is a few minutes of studying, and I love it.
Handling, Rear Wheel Drive, suspension. Sport mode is fantastic, as well as the manual mode. I love it.
Radio speakers stink...and I mean stink. Thicker steering wheel as well would be nice.
