My site also got rejected before with the same kind of reason (low value content). At that time, the articles were written only manually.
What helped me was changing the angle of the content. At first, I had mostly general car reviews, but later I moved more into specific model comparisons (category VS), top 10 lists, and summarized user opinions. After some time, indexing improved, average positions became better, and traffic also started to grow.
The site was approved later, but as people already said above, Google does not bring huge money now anyway.
I think you should continue working on the content, but try to find your own more specific angle. Move away from very general content and make it more focused on something narrow and useful.
