Step-by-step explanation:
According to Jerry Seinfeld, the three letters "LTD" on a Ford stand for "Limited." The famous comedian often uses humor to put a spin on everyday observations, but in this case "LTD" traditionally stands for "Limited" which is used to denote a level of luxury or exclusivity in a vehicle's trim package.
