When the R32 cars went through GOH the front sign that they got was not an LED sign, but a low tech dot matrix sign that you can't see 90% of the time. Also they did get new rollsigns with the route bullet on the lower sign. The side door windows stayed the same size, but the front storm door I think is smaller. Other than this, the cars exterior did not change much aside from the end bonnet. I think it would be great to have a GOHed version of the R32 just as they are heading to a watery grave.
