"Special Edition" models are usually produced at the end of a model's
production run, not so much to commemorate that model but to give a
buyer some reason to buy the "old goods" rather than the immeninent new
model, which in this case, was the new '96 - '02 body style.
The "Special Edition" might feature some free "options" like metallic
paint or special color etc. - additions at small production cost but
that constitute a small bonus in the buyer's eyes.
Obviously it's not much of a point ten years later!
