The 58th Convair 880 is now serving as a restaurant at East London, South Africa.
Also, here in Colorado, there is a little town north of Denver called Erie. . .they had a Convair 990 with wings that served as a restaurant right next to the local runway. I ate there once, years ago, and the next time I went to eat there a few years later, it was gone. It was my only experience in a Convair of any kind. Pretty neat to sit in a four-engined a/c as wide as a DC-9.
