We're actually pretty lucky over here when it comes to cars and taxes. Just like gas is so much cheaper here.
I used to work at LEGO with guys from Denmark. I went over there and even their VPs drove tiny cars. When they moved over here for 3 years, they all bought massive high HP, high displacement cars and trucks. I wondered why they switched, because I thought they were all just green and eco-conscious over there. Turns out they are taxed on cars based on the displacement of the engine. An M3 over there would cost almost as much in tax as the sticker price. Thus they all buy these little cars with 1.5-2L engines. Not to mention that gas is over twice as expensive over there.
Talk about suck.
