One of these days I will have to read up on what happened to Studebaker.
I don't know why they didn't sell tons as they were the best looking cars by far. (IMHO)
Probably mostly bad management, didn't plan far enough ahead. My dad's pet theory is that they built the darn things so well that they ran forever, so folks didn't buy new ones. He ALWAYS bought Studes while they were in business -- and we only got one lemon, a repulsive-green station wagon that just never ran right. He took it back to Baker Motors and they gave him another one. (Ah, those were the days when dealers had personal relationships with their customers!)
The Red Bug (it was a compact in its day!) now lives in palatial splendor in our garage (the SUVs live outside). I drive it around the neighborhood on Sundays and when we go out to dinner we usually take it just to see the look on the valet's face. (They always park it right in front of the restaurant door! That's a place of honor the Stude has shared with a Lamborghini and a Rolls. :-D )
