Nice! I do like the optional 140, & as you said; She is a very solid convertible. & the sport appearance package always looks good on these convertibles. ( rear mount antenna) Thanks for the video on my favorite Chevrolet's.
The front seat belts are the same as those that came new on my mother's 1965 Impala wagon. The rears also look similar to what we had, more of an aircraft style buckle, though ours had a Fisher Body emblem and a crinkle-finish painted buckle, so these may be dealer installed or early aftermarket. Later atermarket belts like on my 1966 Corvair are typically push-button release.
Please PLEASE keep the Corvairs coming! I am so close to being in a position to finally fulfill a lifelong dream of owning one and you seem to have a knack of finding nice ones right here in my back yard [New England]. I'll even take the "ugly ducklings", perhaps one with bad paint fade or interior needs, as long as the frame is solid and the mechanicals are in good shape [I know, but I can dream cant I!]. I think $14.9K for this one is a very respectable asking price for this one.
