My 19" reps have the M badge. Love the OEM 666M wheel. But 20" is too much for my comfort preference. Especially considering how deplorable SF's roads are. I've bent many a wheel here over the years. Happy that I can still get the look, comfort but not the heartbreak when I bend high-end wheels.
Love this thread and seeing the OEM wheels on cars. I get compliments on my reps regularly.
