Depending on what you're cutting out, and what's underneath I'd vote circular saw with the carbide tips, nibbler, 4 1/2" abrasive cut off wheel, or a scroll saw with a metal blade.
Sawzall isn't great for unsupported flat metal, but it'll work in a pinch.
I'd say with all of those except for the abrasive wheel, use cutting wax on the bits often.

1. Sawzall.. seems like thats a good way to vibrate and tear up the paint or potentially end up damging things I dont want to.
2. Cutoff wheel.. if its like any of the cutoff wheel projects ive had before I spend more time waiting for my Compressor to catch up than I do cutting.. and go through a TON of wheels.. maybe there is something better? that has more power? seems like even when I turn the air up to 100 PSI I dont have much power at the wheel...
3. Nibbler.. can a nibbler be powerful enough to cut through the skirting on a bus? is it hard to cut straight?
I dont have access to a plasma cutter or cutting torch.
what do you guys use that have cut rectangular holes in school bus skirt?
