This is starting to sound like you guys are building models of imported toys, rather than models of existing race cars. I don’t agree with the rivet counters, but I can’t see how a “model car” with a lump of plastic under the hood, can even be called a model.

Why is that, OND? I don't think that your definition of "model" necessarily fits with another person's definition of same. It is still a "model" of something, whether it has an engine or not. You must be familiar with the term "shelf model", yes? It is by definition, a model of a vehicle. It is not required to have a certain amount of detail to be considered a legitimate model, in my opinion.
To be considered a model is not determined by the amount, or level of detail. If it does have an engine, but no wiring or plumbing, is it still a legitimate model? If I build a model of the Millennium Falcon, but I leave out the hyper drive unit, is it not still a model of the Millennium Falcon? If I build a model of a WWII aircraft, such as the Supermarine Spitfire, with no engine (which I have done more than once), is that not OK?
I think many of us would still like to see a model you have built. That is not a challenge, OND. It is just nice to see what other builders have done, engine, or no engine. Build on, everybody! And build whatever you want.
