Unable to create new car design

I’ve started building the SUV, but I’ve got no option to name it, or to set a price - hence it’s being sold with zero percent markup! I already produce 4 different models (posh and poverty versions of the saloon and hatchback), have I discovered some limit? I also can’t delete any models.

I demand the option to fleece stupid Chelsea Tractor buyers!

Ah, seems this is a bug. The workaround is to access the models from the Income tab of the Financial Dept page.

100% markup achieved.

dang…I shall look into this…

I have very similar problems.
