Amazon Vehicles
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.<p>At least, that's the theory. In practice you still need to do 100% of the due diligence or you'll end up with spark plug wires that are for the <i>non-California version</i> of the engine of your girlfriend's 2004 Outback, and then you have to build an awkward bracket over the motor because you're too stubborn to return them...
