Hi, All! The Daimler-Benz 770K is a "Touring Car", which is a large open car with a collapsible fabric top assembly. A "Phaeton", designed along the same lines as a Touring Car, is a somewhat smaller, lighter car, with a convertible fabric top, and usually seating five to six passengers. Generally, the longer and heavier Touring Cars can seat up to eight passengers, and they usually have "Jump Seats" which can be folded out of the way ahead of the rear-most seat, or into the back panel of the front seat. The Packard Twelve, on the other hand, is a "Sedan", which is an entirely closed car with a "hard" top, seating five or more passengers. Like the above-mentioned Touring Car, Sedans were also available with longer bodies, which were sometimes referred to as "Limousines", or "7 Passenger (or 8 Passenger) Sedans", depending on body-length or extra-seating equipment. "Town Cars" were a hybrid of the Touring Car and Sedan/Limousine, in that the Chauffeur's forward seating area was open, generally shown in fair weather photos without a hard or soft top. Most Town Cars were equipped with a detachable front roof over the driving compartment, meant for the Chauffeur's comfort in inclement weather. The rear section of the Town Car was an entirely closed seating area, with more luxurious interior appointments as per the Owner's specifications. A speaking-tube was usually fitted for communication between the Chauffeur and the occupants of the rear cabin. In Great Britain, a Sedan is usually referred to as "Saloon".
