In reverse order I would never buy any of these world's most expensive manufacturers cars:

10. Porsche
9. Jaguar
8. Maserati
7. Mercedes-Benz
6. Pagani
5. Aston Martin
4. Bentley
3. Rolls Royce
2. Bugatti
1. Maybach

Why? I could never afford any of them and couldn't care less about owning or driving any of them. I just don't understand the appeal.
