I drove by there last week (1/21-25) and the Alfa Romeo emblem is no longer on the building. And, like Aggie57 stated, there are rows and rows of Jeeps directly in front of the showroom. The location sold both Fiats and Alfas.
I agree that there are no Alfa dealers in Orange County, CA and most of them are located in Los Angeles County. I will still buy a Giulia QV because my two Milanos are very old. I also know that gasoline powered cars will someday be replaced by electric. I intend to drive my gas powered car as long as I am able to.
