I wouldn't worry about the 6-speed in traffic. I've been commuting with my 5-speed here for some time. One good thing about the manual (among others) is you can creep along in 1st in jammed traffic, in gear, and almost never have to touch the brakes unless the traffic actually stops. Forces those behind you to be alert.
As you may notice from my sig. I converted the truck from an auto. Yes the auto is a little less demanding in traffic, however I did notice in hot weather, while creeping, the trans oil temp tended to get uncomfortably hot (had installed a temp gauge). The newer auto's may exhibit the same temp rise. I'll never own an automatic again.
Regarding local area dealers, over the years, I've noticed Fair Oaks Dodge ALWAYS charges 20%+ higher prices for any part than everyone else in the area. Done a lot of comparative pricing for stuff. Parts dept of Lustine Dodge has always treated me well. None of the service departments of the dealers with whom I've done business (Ourisman, Lustine, Fair Oaks, Koons, Manassas) are anything but average. Nothing to avoid, but nothing to recommend.
