Mine is 20.5 feet bumper to bumper and 7 ft wide. I have found that I can fit in most of the "larger" parking spaces without issue. When I can, I will find an empty spot at the top of a T intersection - that way I can easily back into the spot and pull out straight when I leave. If the length is a bit tight, I can back up a bit further so the rear end slightly overhangs the shrubbery.
I rarely ever try to park right up front - too much traffic, pedestrians, etc. to worry about while backing up (either to get in or out of the space). But I haven't had any real problems being able to park.
