I just won a bid on sport seats for the E39. I plan on picking them up in NH this Wednesday. The bid includes: Heated front sport seats from a 2000 540i w/headrests Rear fold down seats w/headrests Side panels (4) with wood trim My E39 doesn't have fold down seats so is it possible to do a simple swap or would the baseboard (?) have to be cut between the seats and the trunk? Is it pretty staightforward in switching my regular seats to the sport seats? I might have B come over next weekend to help me do the switch if he is available.
