The 2002 S-Series cars should be far more reliable than the earlier model years. They are far less prone to excess oil consumption and seem to have far fewer problems. It should last you well over 200k easily. Keep the oil changed regularly and the level checked. Be sure to replace the transmission fluid and filter every 30k to prevent the infamous reverse slam problem, though the 02s have the updated valve body that seems to be less prone to that as well.
I wouldn't trade in the vehicle. Keep it and drive it for at least a few more years.
