I had no idea there were devices so you could play records in a car! I'm guessing they were either too expensive or they didn't work very well. Considering how easy it was for needles to skip, I have to think this was a major problem, not the mention the fact that you would always have to schlep your records with you in the summer because you are not going to want to leave your records in the car on a hot day!!!
Chrysler offered factory installed record players installed under the dash in the mid to late 1950's. It was called the HiWay HiFi, but alas I don't think it worked that well for obvious reason and was gone by the advent of the 60's...
Ah, the car turntable! Even at the time, I couldn't believe this would really work. Imagine how much torque they're applying to that tonearm to keep it on that record! Although, I dunno, Laurel & Hardy had one in a movie, so I guess the design must have been practical.
i actually saw a car at a car show a few years ago with the built in dash board turn table! they had the original promotion material with the car and it was to be used once you got to your destination....

i can't remember if it was a chrysler or not, but i can't imagine too many cars offering this feature in the 50s....
"Plays and rejects up to 12 45's"

Rejects? Is that old-fashioned for "ejects"?
