21. Ford Crown Victoria
The Ford Panther platform is one of the longest-serving platforms in the car industry. Ford first used it in 1978 and it served until 2011, underpinning many models like the Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car.
This chassis proved so sturdy and durable in extreme conditions, so they used it as the base for many police cars and taxis. The design wasn’t special since it was just a plain old boxy American sedan. But even today seven years after they discontinued it, millions of Panther-based models are still on the roads.
