dmc This has a long list of wheels.

That's pretty helpful actually - it's dated 2000 and seems to suggest Coronas, Virgos and Scorpius wheels were still available from dealers (at least in the US) then so presumably could have been specified as an option in 1993 too. I was mainly trying to find out if putting a set of Virgos on would be wrong for the year of the car but apparently not :)
On a side note, I think that document has the pictures of the Corona and Scorpius wheels back to front...
