Acuras are basically high end Hondas, just like Lexus is to Toyota or Infiniti to Nissan.
Acuras are exclusive to North America. One of the arguments presented is that the N.A. climate is colder than other places, and Acura consumers are more concerned about ease of driving than spirited driving.
I went from a G35 to a TL, and yes, I prefer the rwd too. But Acura isn't the only manufacturer building high end fwd cars.
