I guess I don't see why it should be so expensive to do more mix and match options within the same parts bin. The parts are all there already. I think margins would naturally improve with more selection. I see more people do without a feature or two than swallow a package of things they don't want. Especially because it seems more that the people who care about cars the most are the ones the least appreciated.
Maybe that needs to be an emphasis in production technology improvements.
