Yeah, I'm iffy about the size. Parallel parking is key wherever I go ...
Obviously it'll be harder to fit a car like that into tighter spots, but that's not the only determining factor. The lock-to-lock turns (how many times the steering wheel will completely spin around from all the way left to all the way right or vice-versa) plays a role. I believe that the Charger/Magnum/300 all share some steering components with the previous generation Mercedes E-Class (which was also a donor for its transmission and suspension), so you should be able to turn the car sharp enough to get into some tight spots. I drove a 1998 E320 for around a year when I lived on the beach, where street parking is always hard to find, and as long as the space was slightly bigger than the car, I could slip in. With my current Evo (with its fewer lock-to-lock turns), despite its much shorter length I can only fit into spots that are a lot longer than the car itself due to the fact that I can't steer as sharply into a spot. So the Charger might be alright. It's not going to be fun though, if your whole driving experience involves parallel parking on the regular.
