Well, when I was a much younger lad and we visited large cities like New York, my father taught me how to parallel park. From what I gather, the larger vehicle (1991 Suburban, in that case, or 1987 Cadillac in mine) is to put it's front area into the parking space as evenly as possible, leaving the rear wheels on the street. Then, you turn your front wheels to be parallel with the road again and slowly move forwards until your front bumper is touching the vehicle in front of you. Floor it. Move the car until there is room to fit your car in there parallel, then reverse slowly until your rear bumper is touching the car behind you and move it backwards as well, then center your car between them. At least, that's how I was taught. Same thing with our Oldsmobile wagon, as I recall.
