I wouldn't mind car dealers if they actually offered a useful independent service. When I go to buy a camera the person in the store can explain the pros and cons of Canon vs Nikon vs Fuji vs Sony and let me try them all next to each other. Why can't I go to a car dealer and have them explain the pros and cons of Honda vs Toyota vs Nissan and let me compare them right there in the store.

I trust the guy at my local camera store to explain the pros and cons of a Canon vs a Fuji, I obviously don't expect they guy at my local Honda dealer to explain the pros and cons of a Honda vs a Toyota.

Rule of thumb for life: Never ever get advice about what to buy from the person selling it, unless that person has literally no incentive whatsoever, or if the purchase is extremely low risk (e.g. low item cost or hassle-free returns policy).

Camera stores is a great example. The vast majority of salespeople know how to convince you that a product suits your needs, but would have very little clue what is important to get the best outcome. They're not photographers—or if they are, chances are they're no more of a photography expert than you.

Perhaps the worst is "high end" hi-fi salespeople. These slick operators are great at convincing you to buy the unnecessarily expensive product and the criminally overpriced accessories. Unfortunately for the customer, most of the things that matter in making a good system aren't sold in a cardboard box with a big profit margin, so you'll never hear about them from a hi-fi salesperson.
