Finally saw a 06' 330i in Orange County. This is one of the only ones I have seen in a while. I tooted the horn and waved as I drove by and I think they noticed I was driving the exact same car because I could see them point in my direction from my rear view mirror.
First Number/Last three numbers of plate: 6XXX261
Saw driving on North on Beach Blvd. in Buena Park.
