"Imola Red hasn't been offered as a standard color since the E89 Z4M."
That would be since the E85 Z4M roadster and E86 Z4M coupe
The current E89 Z4 only comes in Crimson Red and Melbourne Red
Saw the M6 coupe at the NJ VDC over the weekend. It had just come off the ship. It is the car that will be at the NY Auto Show and it was gorgeous. There was also a M6 convertible in San Marino blue that was stunning.
