Your new car is a beauty inside and out!
I had a '63 Mercury Meteor, which was basically the same car you just got, had factory ice cold under dash air conditioning. Your car is perfect the way it is, in my opinion. It's in better shape, and mine was in super condition. Quick story, in the '60s and '70s Mr. and Mrs. Heinze were church friends of Moms, they had a '63 Falcon Futura two door sedan. Car was totalled in '70, Mr. H. had it completely rebuilt. The car is still four blocks north of here, in the back yard of the house next door to their old house. Still looks pretty good, probably dry rotted inside though.
