I think your right, Catbert. The interior color production numbers do not tie to exterior color production numbers. We can make an educated guess though.
Only 439 coupes (5% of production) were built with Velocity Yellow exterior. 277 coupes were built with the black/red interior (3.2% of production). 3.2% of 439 is ~14. If the numbers hold true, then 14 - 15 2009 coupes were built with your color combination glennkrick.
