This is my third 5 series. I have driven many luxury cars including the S class and consider this car the best combination of size, performance, ride and comfort currently on the road. Also, the car's brakes are terrific. The 525 engine lacks a bit of power but the 5 speed automatic (with manual mode) makes the drive lively. The 530 more than makes up for this "issue" and the 540 is a Porche killer.
