This might be more appropriate for a "What my M3 cannot do."
And I've only tried this once, with no success:
Is it true that the instrument lighting (speedometer, tachometer) can NOT be adjusted while the M3 is in motion?
I was driving one night between Houston and Dallas, and reached the outskirts (aka The Middle of Nowhere) and wanted to dim the dash lights -- but I couldn't get the option to appear -- not until the next day when I was sitting in the garage. Or was I fumbling the BC selection?

When one wants a cabriolet, is there really any other choice than an M3? No. No, there's not.
