My loss is your gain...Brand new bought off Ebay two Beige Cream color for E90/92 series.
I was suckered to believe they were M3 seats but are not. Never used still in wrapping.
If you are looking to replace your worn out buttom cushions with a fresh look, this is your answer
Seats have the heating wire element . I paid $650 and willing to take $450 for both.
