Is there a good page that explains what changed in the 240 from '80 to '93? There's some info about the '90-'93 model year differences at consumerguide.com but otherwise good info seems scarce. I know that the 240 picked up a driver airbag and then later a passenger airbag sometime during the 80s, but I don't know the years. As far as I can tell from looking at photos, the '86 has a revised headlight style from '85. I haven't yet found a page that explains the trim levels like GL, DL, et cetera for all the 80s model years and what the yearly changes were.

In general, does a late '80s 240 offer anything worthwhile over an early '80s 240, or a '90s 240 offer anything over an earlier one? From all I've read on these forums, the answer for most owners seems to be no as long as the condition is maintained.
