Well I don't have much to say on this one. Except that I take my car to Fletcher Jones! I'm practically there daily for something or for one of my friends! Actually, I'm trying to not go as much, I feel kind of stupid!
But yeah, Newport Beach has the most MB per capita than any other city in the world.
As for FJ being the biggest dealership in the US, it could be, but I've never heard that. I do know that their dealership is huge though; they have tons of cars on the lot, and just as money in storage up top. And then they rent out (?) this parking structure (top 2 floors) across the street that is FILLED WITH MERCEDES. When I get my digital camera, maybe I'll take a picture. So they're big, but I don't know HOW big.
I would assume that the tech would be good coming from FJ. But their service still isn't up to standard. Well the physical aspect is... with the marble showroom, the putting green out front, the full service bar and 'waiting' room, internet access, children's playroom, Collection store, NAIL SALON (!), shoe shining, and appointments that are nicer than most places I've ever been to.
Just my .02. Check
