It’s a well known fact if you’re remotely interested in cars. Mazda has supposedly upped their game lately regarding rust, but they and other Japanese brands are still regarded inferior to Volvo/german cars in terms of falling apart to rust in our Nordic climate.

You can use car.info to if you want to dig further on this (statistik på skrotade bilar). Or just ask your favorite LLM. You don’t have to take my word for it.

Japan doesn’t salt their roads nearly as much as we do.
