I don’t know much about cars either, but that does happen. For example, Cadillac Escalade was/is based on a less-fancy-looking GMC SUV (Suburban?). Chevy Volt is also Cadillac ELR (different body and interior, same drivetrain), Opel Ampera (in Europe), and Buick Velite (in China, because Buick has a better brand recognition there)

Some cheaper car models come with variety of “sport editions” and out-of-factory tint and spoilers, which would be the equivalent to the RGB computer peripherals that you mentioned, and appeal to specific customers.

TBH I don’t know why some expensive car designs are perceived as “fancy” or “impressive”. I think they are mostly boring. And quality-wise, anything above bottom tier would have materials that last decades now.
