The solution is to add a term to your motorcycling, "transitional ownership". Think of it as a way to retain the Norge, sort of like a compass or direction setter as you move into and out of the restoration periods of older Guzzi s and through some period of enjoyment before heading to the next. Rinse, repeat.
That is if you'd like to keep the Norge and somehow justify the others. The Norge then, keeps you rooted in reality while the others let your fantasy's play. Best of all worlds.
