This intriguing vehicle is a WaterCar Panther, produced by California-based Fountain Valley BodyWorks and sourced from an Acura with a 3.7-liter V6 engine. It's a remarkable one-owner amphibious car from Plymouth, Massachusetts, capable of reaching approximately 85 mph on land and 45 mph in water through its unique marine jet drive system connected via a transfer case to the rear-wheel-drive four-speed manual transaxle.
