How many Mercedes classes are there?

Mercedes-Benz produces several classes of vehicles, which can be further divided into sub-models. As of my knowledge cutoff of September 2021, Mercedes-Benz has the following main classes of vehicles:

1. A-Class
2. B-Class
3. C-Class
4. E-Class
5. S-Class
6. CLA-Class
7. CLS-Class
8. G-Class
9. GLA-Class
10. GLB-Class
11. GLC-Class
12. GLE-Class
13. GLS-Class
14. SLC-Class
15. SL-Class
16. AMG GT

It's worth noting that Mercedes-Benz occasionally introduces new models or discontinues older ones, so this list may not be exhaustive or up-to-date.
