L.A. is freakin' huge, so whomever had "only one" here probably only had the title for a day or two. When I got my FX in November, they were still pretty rare (especially my Liquid Copper), but today, I must see one a day, and they're even all over the 'hood- I saw this really cute woman in a Graphite (? the "silver" color) '35, but I didn't get a chance to admire her chassis.
I think you'd have to live in a small town or away from the city. At work there are two other FX's and around where I live, I frequently see three or four. But so far I haven't seen any other red FX's like mine.
