You also need to think about what percentage of the surviving 1955 Kaisers may be listed in the Registry.
If only 50% of the surviving cars are in the Registry, then there are 72 surviving out of the 229. If only 25% are listed in the Registry, then there are 144 surviving out of the 229. (Hopefully my math is correct
, and understand that this is just a "what if".)
From my experience on the Studebaker side, only a relatively small percentage of the owners usually get their cars listed on a Registry. Some don't like others to know what they have, others don't even know there is a club, and others don't even care. Of course, there are exceptions to this - Avantis for example have been the benefit of a very significant effort to find and list the surviving cars as well as the salvaged/parted out cars. The original Shelby Cobras are probably another example. High value cars like Cobras will have a high percentage of existing cars known since being listed on the Registry would most likely be considered as a 'verification' of authenticity and would be important for the owners' investments. I would bet that Darrins have a significantly higher percentage of cars listed/know, because of their much higher value.
It would be interesting to find out what the Kaiser/Frazer/Darrin Registry keepers' estimates would be of what percentage of the surviving cars are listed on the Registries.
I would not be surprised if a higher percentage of '55 Kaisers might have survived than earlier yeas of Kaisers. Again, I use a Studebaker example - there seem to be a higher percentage of 1964 GT Hawks surviving than the '62 and '63 GT Hawks. Many chalk this up to the '64s being the 'last of the breed' of Hawks. (I'm sure y'all are tired of me using Studebaker examples, but I know a lot more about them. I'm still learning about K-F's and don't own one -- yet
.
Of course, this is all my opinion only. Other opinions & comments are of course welcome - this is how we learn and gain insight.
