The Mercer was named for the New Jersey county where
it was made. Powerful, fast, and favored by celebrities and socialites,
this luxury sports car sold for about $3,700. It was made by the Mercer
Automobile Co., run by the Roebling family (known for producing wire cables
for the Brooklyn Bridge decades earlier). The company sold more than 25,000
Mercers between 1910 and 1925, when it stopped production.
