It took me about 1 hr to unbolt and unplug the old seats and to rebolt and plug in the new seats, however my steering wheel wouldnt move and my airbag light came on...

I bought the E46 seats on ebay, I have been waiting for black seats that were in good condition and to have heat and lumbar for awhile. X5 sport seats are nearly impossible to find anywhere, E46 seats however are a bit more ubiquitous.

Not sure what I am doing with the old seats.....they're basically 3 series seats now. I may just sell them as that, I was considering removing the bench in the back and installing them in the rear, but the seats are too high installed so I wont be able to go with the 2+2 arrangment.

This was a one man project, the seats are about 50-75 lbs and not to hard to move in and out with care

Other than the costs of the seats, it wasnt expensive, I cut my hand up a little bit trying to remove the side pieces, they have hidden tabs that are extremely difficult to work with.
