"wow is that olds a convertible? or may be a landau roof???"
Landau roofs were only seen on autos from a Show Car or Custom Bodied or latterly "customized" by owner perspective. One of the problems with a "Rag Top",
aside from fabric roof failure usually due to the rotted stitching giving way, was that of the clouding and then brittleness of the zippered-in, plastic rear window.
Most convertibles would end their life with no window and it's behind the rear seat storage area filled with dead leaves/water/snow.
Other items to note are while the Chev is being gassed, it is at the B-A (British-American) Regular "88" pump while
the Olds is at the the unseen Super "98" pump; the Chev is a "Stove-bolt" 6 cylinder;
the Rag Top, a OHV V8. Also to note, is the manner of which the attendant's sleeves are rolled-up; classic!
IF only I had of questioned then, for the answers needed now . . .
