Yes, only solid blue, not two-tone - not with a cream-white room. He lived at home for awhile after her returned from the air force and I used to help him wash the Caddy in the front yard. I went with a drive in it with him a few times before he moved into a place of his own.
Then, sad to say, he had an accident, totaled the Caddy and shortly afterward bought a Corvair (OMG!!! from a Caddy to a Corvair!!!!) and moved 700 miles away.
Corvair Spyder
Imagine though if they had come out with a model that followed the concept version:
We would all want to have one for sure.
BTW, the name Corvair is a mixture of the Corvette & Bel Air.
