read through that. it will tell you equipment and equipment changes per year.
the 3rd gen has a lot of options in that you can get it stick, v6, i4, leather, cloth, 4wd, 2wd, base, fully loaded, upgraded sound, crappy sound, 15 inch rims, 16 inch rims, etc.
if i were you id read the history, and start the hunt. whats your price range? the most popular choices (as far as height, equipment and technology) are 99 and 00 4wd's, because they sit an inch higher yet benefit from the upgraded headlights and better/newer overall equipment.
sounds to me like a 99 or 00 sr5 is your next purchase
good luck.
