I generally sit on benches, but not groups of cars, so your right.
A fleet of cars or a car pool.
A group of cars and other vehicles under the same ownership is called a fleet.
Two words can be used, either a Bench or a Sentance
A fleet.
The collective nouns are:a bench of judgesa panel of judges
A Model. a fleet
I do not believe there are any cars made in the United States that have a bench seat option any more. It is a safety thing.
Referred to collectively as "The Court" or sometimes "The Bench." If the judges are working together, as they often do on appellate courts, they may be called a "panel."
Toyota Avalon, Ford Crown Victoria, & Mercury Gran Marquis all had bench seats. The Chevy Impala had the bench seat as an option so it may be hard to find one. There were some Mercedes and BMW luxury cars with a bench seat but again probably hard to find. Ford Crown Vic will be the easiest to find and they are dependable cars.
