Milt,
No such thing as a RWD Aurora. The basic chassis was a downsized version of the Caddy STS. Tight inside, almost as small as an older Jag sedan. (of course I'm 6'2'' so I notice that sort of thing) A friend of mine has one & loves it. Takes it down to Florida every winter & has to work to behave himself on the interstates.
Seeing as how the Olds nameplate is no more, you should be able to find an 'orphan' around somewhere. There are always people who get turned off about the people who sold them their car not 'being in business' any more. I don't think GM will fold for a while yet
Good luck
Les
