I was wandering if it is possible to take leather seats from a 1991 mercedes benzAnd place it into a 1987 325e? No ignorant a$$holes telling me bull$hit If you don't know don't post straight up

 

Id say get a tape measure out and see if the seats are close in dimensions. I really doubt its been done.
Also are your seats flat.. or the recaro style. They should be the flat ones. But alot of cars get seats swapped over the years.
Why wouldnt you just swap out the complete seat.. put the Merc ones in the BMW?

There are sellers on ebay that sell new skins made for a BMW model - seat. I just got a set for the Z3.

 

They wont fit, Mercedes seat are wider. You could fit E36 M3 or 325is seats in the E30. You need to fabricate some adapter brackets though.

 

Jeez im postin a bit late, but you could do mercedez or you could put BMW sports black leather i have the whole set front and rear, and im selling it.

 

Mercedes seats are wonder and i like Mercedes Ben's s series engine,rod grip,staring wise also good for smooth drive.
