This sounds for me a very Obama hate(?) conclusion. If it's really Obamas fault, why does this happen in many other countries as well?
Living in germany and italy in both countries I see the exact same trend.
I myself drive a sedan, a Volvo S60. It is a gorgeous car and I always get compliments for it, but the seller (who is a very big one) only sold one S60 in several years. It is also the least sold car by Volvo, as far as I know.
So how is this Obamas fault again?
