I agree with euro cars but there are some exceptions with BMWs. Some colors ended with the 2800CS and new colors appeared with the 3.0CS. And when the 74s came out, some colors ended and more new ones were released. This included the euro coupes as they switched to the 43xxxxx VIN nomenclature.That makes sense for DOT/EPA requirements. There has to be a line in the sand (or calendar ) for those items in order to insure compliance.
