There should be statistics how many cars are sold and then you could collect data from repairshops instead of users from a website. Even if a user has 3 cars, asking 1 repairshop will give you data for 100’s of cars. Its just odd to do a survey on the users of your website because thats probably a small and skewed sample size.

Edit: “We had insufficient data to create brand rankings for Alfa Romeo, Chrysler, Dodge, Fiat, Infiniti, Jaguar, Land Rover, Lincoln, Lucid, Maserati, Mercedes-Benz, Mini, Mitsubishi, Polestar, Porsche, and Ram.” Gives you a hint on how sufficient their data is in total.
