I'd really get an S60R over the S80, but the S80 would be my choice. I know two co-workers that have and love them. Best interior of the bunch. The X-Type is great with $6500 in dealer cash (IIRC) + A-Plan, but the options to make it worthwhile push the cost beyond what it is worth. I think they downgraded the leather from 2002 as it doesn't look/feel as nice as I remember when I was shopping.
