Power left seat?

Was this an option back in '73? I know there were power windows available, but I've never heard of a power left seat...my recently acquired COA has some questionable/vague listings:

"With spoilers" (which probably refers to the "S" front air dam, I think, but why it's plural boggles me)
"Hi-Fi Sound System" (plain-jane radio or are we talking upgraded audio here?)

Anyone ever see any of these types of vague descriptions? How do they go about correcting errors?

Kalied,

Power seats were not an option until '85

However,
What the U.S.A. imported cars did have in '73 was a seat cushion sensor that was connected to a red seat belt warning light on the dash... for both seats.

Sorry, not much help
