The problem is just there is no concept of a car company where they only sell their standard mass market vehicles. Somewhat more expensive higher margin vehicles are in the lineup for almost all the other companies. Its kind of strange to suggest its not worth it when it is seemingly worth it for most other companies.

Maybe the wisdom of having a 'full lineup' is wrong and has to do with making dealers happy.

On the other hand, having 99% of your sales be 2 very similar vehicles seems questionable strategy.
