The level of standard equipment. The exact items may vary by year, but the SE likely included nicer seats and trim, maybe better wheelcovers.

All Depends on the year..81-84 SE was the top of the line

1985-1986 The SE was the middle priced K. The seats were better than the base and in my opinion attractive, especally if you opted for an all blue vinyl interior.

The 13 inch wheel cover was standard on the 85-86 SE, 81-83 had fourteen inch.

I was asked if my 86 was an se when I was looking for strut springs, couldn't understand why​

in that case, I would guess suspension tuning is different between trim levels. That is sometimes the case.
