Wouldn’t really make any difference, as each model represents a sample of 10,000 cars.If you count all BMW 3 series as one type, it heads the list with well over twice as many as the Prius.
All it would do is average them out to a more mid-table position overall.
As said, the data says a little about the cars generally, but probably speaks greater volumes for the typical drivers of those cars. Prius=taxi, driven as suggested already and often covering very high mileage with minimum maintenance (budget tyres etc).
Small french hatchbacks = young kids
Rover 25 = people who should have given up driving years ago but need a car for their weekly trips to Tesco etc.
BMW/Audi brigade, as you know
