This is why I really don't "get" doing suicide doors. It adds nothing but a "wow" factor (notice it is a small "wow", not a "WOW") and it is only seen when the car is at it's least attractive time....when the doors are open. I feel the time is way better spent on mods that inhance the looks of the car as it sits there or is driven by.
If you trace the suicide doors back, it was done as a "fix" for "a mod that WAS done for the looks of the car". The auto stylists of that time were trying to go with the swept back body lines to mimic speed & motion. They angled the cowl to hood parting line and then angled the nearby front door edge. Then there was no way to mount hinges on the severe angle...and the suicide door was born.
I believe it was 1932, with the Plymouth PB. Ford had the doors on the 3 window only, but with a vertical hood line. Ford in 33 did what Plymouth did in 32...a slanted rear hood line too.
I owned a 32 PB cabriolet and I did not care for the suicide doors. Making a front angled door requires it to be much longer & heavier. It just felt heavy & clumsy.
