I do door and trunk jambs first, then engine area (mainly just spray, no really washing, maybe some on jambs and plastics), then roof and windows, then side windows/top doors, hood/hatch, lower doors, bumpers, and wheels on the very last.
If you're really nuts you take off the wheel and wash both sides heh. I'm only semi-nuts and just do that when rotating tires.
As for two buckets and so much attention...
NOPE. I just wash my car. Since the day I bought it I washed it maybe 3 times, plus one time in a car wash. That is since November 2016.
Having things to do around the house, having two kids, and wife... not much time to wash the car every month.
