here's my faux attempt at 'security':
yeah, i'd never actually use the fire extinguisher, and the airbag's not connected (car didn't originally come with one). i've got a triangle in the trunk, too, but again, prolly will never use that either. as for abs, i believe it came out in, what, 1981? which makes half the w123's uneligible for it.
but i was always under the impression that it was the other way around--that in the US, we got all the avaialable options standard, whereas in the rest of the world, each item was a la carte as an individual option
