I think it's become pretty much agreed upon that model or options have no impact on the build/delivery time. I'm also in Philly, unfortunately, having reserved in early Nov of last year and having received my car 9 months later in August, quicker than most other reports. I think it's a Philly thing: we are not the brightest, most well informed people in the nation. If anything, we, as a rule, are followers, not leaders, who will catch on to the phenomena that is smart, oh, right about the time most of the rest of the nation has tired of them. Generally, to know of smart cars, you have to know how to read. Philadephians, don't! I guess the wait time for us now, has slipped to 6 months. (You'll notice, smart didn't even assign a dealer within Philadelphia limits: they've done their homework!)
Be glad you're able to take advantage of one of the few benefits of living in or around this city: quick delivery!
Enjoy your car. I sure enjoy mine!!!
