My father's thinking of buying a new car and I'm trying to do research online to help him make the right choice. The issue is that I can't find any research whatsoever. All I get are subjective reviews (which seem to be just marketing ads) and anecdotes. I can't find objective information on which car brand or model is the best. Isn't this scary because it means that car manufacturers don't have any incentive to improve their cars? Instead, they only have incentive to work on advertising. He's thinking of buying a Mercedes B200. I'm trying to do research on Mercedes compared to Mazda, Honda, etc but I can't seem to find any remotely scientific information.
