What distinguishes the interior of the E12 M535i from that of a standard 5 Series?
Though it shares its basic design and layout with that of the standard E12 5 Series, the interior of the E12 M535i contains two special features: Front sport seats made by Recaro covered in a unique corduroy fabric, leatherette or optional leather (ASS sport seats in black cloth with central Motorsport stripes were also available by special order) and a three-spoke leather-wrapped steering wheel featuring the BMW Motorpsort logo, identical to the one used in the M1 sports car.
