The "Fintail" (German: Heckflosse) was a series of luxury vehicles produced by Mercedes-Benz from 1959 to 1968 under the W111 chassis code. Though never officially designated as such (they were designated Peilstege, marking the end of the car in rear view mirror), the cars gained the nickname because of the distinctive rear-end which incorporates small tailfins, thought to be an understated attempt to appeal to the United States market at the time (with domestic finned cars, such as the Cadillacs and Buicks of the times).
