The domestic scene (excluding muscle cars) is lame. It might as well be called "Dead platform tuning" or "Out of production domestic eco-cars fill in the blank." I forsee it being a lot of low budget american junk (like autozone special Corsicas).
Lets be honest. There is only so much you can do with non-muscle american, because of how little there actually is. Article worthy cars could be covered in 2 years worth of mags. or less. If the cars are that great, they could get into any existing publication.
