Toshi- there was a magazine whose name escapes me right now that featured build reviews of models that were not painted. Or, obviously, puttied or otherwise had "body work".
It was a really useful thing. Airplane forum I think.
Beware, there's a tendency in the PE industry, esp. "Lion Roar", to feature unpainted models with the PE installed. It's done to show off the PE, which is fine, but it isn't the way to build a model.
