What distinguishes an M roadsters interior from that of a normal Z3?
The interior of the M roadster features several unique items including a chrome-ringed instrument cluster with red needles and the M logo, three auxiliary chrome-ringed gauges in the center console, power and heated sport seats with special pleated leather trim (monotone black or two-tone), a 375mm three-spoke M steering wheel with tri-color stitching, an illuminated M leather shift knob with the M logo on the shift pattern and a chrome boot surround, an oval-shaped rear-view mirror, leather door pulls and center console trim, chrome inside door handles, and door sill plates with the “M” logo.
