There is much talk on the e39 board about 540 owners that covet the M5. I suspect that many on this board are prior 540/6 owners..it is your opinion that I solict.
As many consider the 540/6 an M5 Lite, I wonder if any of you prior 540 owners would consider going back to the "Lite" version after owning an M5. Other than price what might motivate you to do so?
