Your Opinion: Age of driving?

On another topic, I came up with the idea of asking the people here according to your opinion about the age of the driver corresponding to which BMW. So I am of the following opinion: 20-30 years = 3’s 30-45 years = 5’s (alternatively 40-55 years = X5) 45-end= 7’s If the 25-year-old is seen with a 7’s, everyone says: “…and how does it go in Papa’s car”! Conversely, the pensioner in the 3’s also looks kind of stupid. Touring, whether 3s or 5s, suggests family or field staff. What do you mean…? Which BMW fits what age of the driver?
