Before you laugh that you'd never use this to buy a car, it may be worth taking the time to find your make/model and add it to your "Garage" on amazon. Amazon will then try to confirm or not if the cabin air filter you are about to buy is a correct fit for your car. Amazon tries to do the same thing with camera gear. At least, that's the theory. In practice you still need to do 100% of the due diligence or you'll end…
It would be nice if they fixed this problem. I saw a ton of parts that incorrectly said they'd fit my vehicle. Windshield wipers are an easy example. You'll see varying length wiper blades they say will fit.
Edit: It seems like they could favor search results matching specific vehicles to combat this. For example, a part should be viewed as less relevant for claiming compatibility with more vehicles. This would be problematic for universal stuff like tires, wiper blades, and other accessories, but I'm sure they could differentiate between the legit universal stuff and the seller's who claim their part fits every vehicle in existence.
I'm sure this is harder than I'm making it out to be, I can't imagine all the edge cases they have to deal with. But some effort would really help, and I'd be more likely to buy this stuff online if it wasn't so damn difficult to verify that the part is compatible.
