Per my original window sticker, sport seats were listed under standard equipment.

Leather seats are listed under options at no added cost. My interpretation is that at least the 2002 4.6is were all built with sport seats and that there was at least one other choice for material used on those sport seats that could have cost more, less or also included in the cost.
