These unit were tested before removal and are in great working condition. 

The gears are in great shape with neither of the units having missing, bent or broken teeth. 

They do not chatter going up or down either. 

The connectors are in great shape as well with no missing, broken or bent pins. 

The wires are not cut or have been spliced into. 

These are genuine OEM BMW units.

These units will fit any E28 (528e, 533i, 535i/iS or M5) from 1982-1988. 

These are also a great upgrade for people with any model E9. (plenty of writes online how to retrofit them). 

PLEASE MAKE SURE THESE WILL FIT YOUR VEHICLE BEFORE PURCHASING!!

Thanks!
