nah. irvine subaru IS the #1 wrx dealer in the country, if not the world, selling right around 100 wrxs a month since it was released if i'm not mistaken. however, subarus are not nearly as popular in southern california as they are in other states like washington and other parts of the US where there is more "weather" than in southern california.
but it would be interesting to see who the #1 dealer in the country is. please post if you have the info, thanks.
