"But, I was wrong. It was actually the 1948 Hudson Motor Car Co., that introduced the modern car."
Not sure about that comment... The Packard Motor Car company was rivaled to be the first true American Modern Car...
Packard had quite a few modern appliances that introduced on their vehicles...
Like Air Conditioning, The Modern Steering Wheel, and the almighty 12 cylinder engine...
Well I am biased, they were a tank in the late 40's but talk about luxury!
My favorite was this one: The 48 Super 8 Convertible!
