Great-looking car. Is that original paint?

Have you also compared the pricing for both options? I cannot imagine that fitting/prepping/painting a random new door will be cheaper then doing a little patch.
Regardless of the car's overall originality, the original door will likely allow for a better quality repair in general.

Sorry for a bit of an off-topic - did you sand and polish your repaired fender bottom? There is "orange" peel, which can easily be fixed with a bit of extra work

1941 - there are better cars available for this price.
1956 - I see potential bondo at the rockers and rear fenders, considering that the car is from up north, I am not very optimistic :(

I would also recommend keeping the door on the car, for the entire repair process. Just removing the interior door panel should give plenty of access...

The hole, sort of, looks like an old-school large caliber projectile impact... Regular body damage usually looks sloppy, while some interesting impact marks (like an elephant foot print, etc.) could potentially compliment the car's original history. I could definitely see this one as a nice conversation piece How often do you see a hole in the door like that? While the rest of the car looks presentable, you can actually get away with it, by cleaning the yellow paint off and protecting the metal around the impact so that it does not rust.

This is definitely a fix, in my opinion. Why would you replace a perfectly fine OEM (I assume) door, with another one, over a minor damage like this? Doors from different cars do not necessarily fit well, and it will be non-original to this vehicle, etc.
Heck, you can even remove the paint transfer marks, and leave the hole as is (assuming you do not drive in the rain/elements). It kind of looks cool, as opposed to your regular body damage

That is not necessarily accurate; it depends. The higher RPM (within limits), by itself, does not means more strain on the engine. Usually, higher RPM and speed, if anything, reduces the engine temp because you are ventilating the radiator and circulating the coolant better.

First order of business, when you get the car, is make sure that the system is not clogged. Specifically, check the block drain etc. In my car (non Packard) a wrong thermostat was also installed by the PO, so the car would take forever to warm-up and then overheat

And the saga continues

Are you planning to come-up with the asking price, at some point? I am afraid that "taking offers" is against the for sale forum rules.
Also, a link with plenty of high-res pictures, and especially from underneath, along with the description of what has been done to the car and what is/is not original, could certainly be helpful.

That last one will be for sale forever, like so many of them
And as I found-out, simple words like "body work" or "painted" or "restoration" have an extremely wide-ranging meaning when used by different people.
