That’s just what they want you to believe. Cars have to be 25 years old before they can be imported, because Mercedes dealerships where butthurt about ⅕ beamers being imports four decades ago.
Technology connections on YouTube touched on it in a video, if I recall right domestic sales went up a couple percent for Mercedes dealerships, no where remotely close to +20%.

Since we’re dealing with hyperbole, and I know this will sound preposterous, but what if had companies and the filthy rich pay their fair share of taxes 🤣
