superbleu, I think your idea is sound, however, I believe the car manufacture model used today has changed so much that it is not able to handle the dynamic of customer input and limited production it once was. They are geared more for extended production runs in auto-pilot rather than manual operation. The production model today is designed to cater to the masses rather than individuals. This is why they offer "option groups" rather than "options"... it's all about streamlining. There has probably been untold amounts spent on research that indicates "sublime" and "plum crazy" and "go mango" are poor market choices, and these loser would never sell... regardless of what the customer wants... err... thinks they want...
