The car pictured in the ad does not have a '55 hood scoop on it so it's doubtful that it even is a '55. Many CL sellers go by what they think it is, or by what "a friend told me it was..." A '55 Kaiser has one distinguishing feature - a higher center fin on the hood scoop and a couple of smaller ones to each side - the car in this ad clearly lacks that feature so unless the seller posts the tag / serial info I seriously doubt it's a '55. The seller may have seen a '55 pictured somewhere and concluded that's what he has but did not notice the hood scoop was different. Unless I saw the tags, I would not pursue this one if I was looking for a '55.
Regarding how many were white, if you look at the picture of the car where it shows the driver side front fender you can see the white has flaked off and under is the original green paint. You can also see this on the hood where the white has worn through. It looks like Tropical Green - a lot of '54s were that color.
