Rarkrat,
In all the factory "sidekick" "factory brochures" I have, including for "89" (although have another coming soon, possibly here tonite), I've never seen "SLE" for a sidekick. I'm guessing you have such a "designation" somewhere on the outside or inside of the vehicle? If so, could you post a pix of it. I've seen with many different vehicles where a dealer or dealer chain "customize" vehicles with some trim options (wheels, seats, etc) and add "badging" of their own seperate from factory packages.
LSi, however was a factory or at least Cami tracker thing, seperate from what Suzuki had for their "un-rebadged" cars. What was standard, and what was "optional" changed by years. "special" seats was a common thread through the years. "base seats" in both sidekicks and trackers were one-piece "backs", cloth centers, but vinyl "trim", and the upper "grades" having adjustable, seperate headrests. Suzuki even had a third (more upper grade) with a slightly different square open center style headrest.
To quote an 89 tracker brochure: "The Geo Tracker LSi is not a luxury car. But it is (undelined) a very dressy, very comfortable way to go four-wheeling.
LSi equipment (not available on Tracker convertible) (*their parentesis) includes:
Air conditioning Chrome rally wheels Intermittent windshield wipers Rear window wiper washer Spare tire cover 3-speed automatic transmission Tinted glass white-lettered on-/offf-road tires.
On the inside, this Tracker offers a whole new look, with the following features: Fold-and-flip rear bucket seats with recline feature. Fully reclining high-back front bucket seats with "see-through" adjustable head restraints. LSi Custom Cloth interior trim. Molded accoustical headliner"
All of those were available as well as other options (6 listed) available on all tracker models. (pg 12). So, for 89, "LSi" was hard-top, and 4-wheel drive with A/C "standard, as well as some special "trim" features.
