I have never owned an early model car. I was wondering about the interior room: Mopar vs Ford & GM cars in the late 20's & early 30's. I've heard early Mopars were all steel while the others had a lot of wood inside their structure, it that true?

Were the Mopars wider across than others at the dash area, making for more foot room?

How about the front seat area, where the Mopars broader, making for a wider more spacious seating area?

Thanks,
John
