Packard was one of the first luxury brands in the US, and was the only independent luxury car company to survive the Great Depression - unlike Duesenberg, Pierce-Arrow, Peerless, Marmon and others.
During World War II, Packard built the Merlin engines for the P-51 Mustang fighters, under license from Rolls-Royce.
Packard built the first production V12 engine in 1916 - called the "Twin Six". Enzo Ferrari was so impressed by the power and smoothness of the Packard V12 that he decided to put his own V12 engine in his road cars.
Although Packard sales started declining after WW2, the company was still strong enough financially to purchase Studebaker. But Studebaker required a lot of cash to stay afloat; so the Packard and Studebaker lines started sharing more and more parts, until by 1958, Packards were little more than re-badged Studebakers, and Packard was killed off.
Oh, and speaking of Studebaker - how many people here know that if it wasn't for Studebaker, there would have been no Mercedes-Benz in the US? When Daimler-Benz was looking to expand into the American market, it didn't have the money to create its own dealership network. So it partnered with Studebaker to sell its cars in the US. That arrangement lasted from 1958 to 1966, when Studebaker closed its last plant in Hamilton, Ontario. Many dealers converted their dealerships from Studebaker/Mercedes to Mercedes only.
