Sport seats or no?

I'm looking at a 2001 530i with the Sport Package. I test drove a 528i with the Sport Package and was a little disappointed in the seat comfort. I didn't play around with the adjustments much, though. I have not driven a 5 series w/o the Sport Package. Is there a big difference in seat comfort? Should I be waiting for a non-SP 5? I drive 130 miles r/t to work every day, so comfort is a big thing to me.

Thanks.
