Can you explain?
Happy people are more likely to buy Tesla?
Happy people are more likely to buy Tesla?
* People with more money are more likely to buy a Tesla
* People with more money are more likely to be happy
Also, while I believe that money leads to happier people, I'd imagine people with who spend more money on a car are likely to be more demanding/particular about they want out of that car (e.g. I was very forgiving with issues with my used mini cooper but I get pretty annoyed at most issues with my Model S).
