Lots of cars have adjustable interior lighting, but the Ford Mustang takes top marks for the sheer magnitude of different colors on offer. With the scroll of a button, the Mustang’s gauge cluster can be tuned to one of literally hundreds of hues. This should really be the default sports coupe for any manager of a Sherwin-Williams or Benjamin Moore paint store. What’s even wackier is that, in a weird way, the Mustang’s interior light show really works wonders depending on the mood you’re in. Feeling racy? Switch the gauges to a fiery red and stomp the gas pedal. For relaxed highway cruising, opting for an icy blue or forest green helps calms things down.
