I don't think it really matters a lot about this brand ranking as many owners have more than one car. A car rental company will perhaps buy a certain brand or a business might decide to go for one particular make and these decisions are based on practicality and brand reputation. It is more important to know what brand of cars the business owner and the well-to-do drive, not based only on the car being cheap and good. No one will deny that the Toyota is a good and reliable car, and it only confirmed what people already know. For many other owners of different brands, they will want to be seen dead in a Toyota no matter what.
You might as well ask what colour panties most women wear but for most men, they would want them to take it off as colour does not matter but what it covers does.
