From what I know, the Trofeo was a package on the Toranado, like the SSE is to the Bonneville.
The Trofeo did have the touchscreen, but I'm not sure what years it was in, although I know that they had them in 1988 -1987 and 1986....
The restyle on the Toranado took place with the release of the 1990 model year.
With the pre-1990 Toranado I am not sure as to what all was done to the outside of the Toranado'* with the Trofeo package.
5 years ago I would have this off the bat, as my brother had 1988 Toranado and we did a lot of research on them, but now I kind am drawing a blank beyond what I said above.
