I like this one a lot. Better than the UrSaab and the two other modern reinterpretations at the linked site.
The C-pillar is way thinner and tailights (plural!) are better integrated. But more importantly the underbody has a proper diffuser and I'll bet there is less turbulence exiting those front wheel wells than those huge gaping holes facing downwards on the Ursaab.
arcosine -- If those wheels are the only cooling fans for the engine, I could see it.
