Among BMW’s lowest volume production cars ever, a total of 678 U.S. specification S54-equipped M Coupes were produced featuring a 5-speed manual transmission and a limited-slip differential. This example is one of only 51 finished in Estoril Blue over Estoril Blue & Black Nappa leather and of those, one of 38 to have been equipped with a sunroof. Modified with a Dinan Stage 1 tune, this M Coupe is now being offered for auction by its seller out of Colorado with approximately 88k miles showing on the odometer.

Designed to increase the torsional and structural rigidity of the Z3 roadster’s chassis, the M Coupe only borrows the body panels ahead of the A-pillars. However, it can be distinguished from the standard Z3 by its revised front fascia, widened rear fenders, and side air vents. This example comes finished in Estoril Blue (335) and features a sunroof, replacement black kidney grilles, and added magnetic stone guards, and rear wheel spacers. It rides on refinished 17” Style 40 wheels dressed in Michelin Pilot Sport 4S tires from 2023. The seller notes the hood and front bumper were refinished and the roof was touched up by the professionals at Eurocars Collision in Colorado. A carbon-printed wrap was also applied to the roof and the seller recommends refinishing the area. Detailed images are provided in the gallery along with a clean CARFAX report.

The cabin offers Estoril Blue and Black Nappa leather (Q6ES) upholstery. Equipment includes power-adjustable heated sport seats, a leather-wrapped M steering wheel, air conditioning, cruise control, a BMW Business CD stereo, a trunk-mounted CD changer, and a Harmon Kardon sound system. New floor mats have been added, and modifications include a ZHP shift knob and a LeatherZ Mark 1 armrest with Homelink. The seller notes some scuffing on the seat bolsters near the seatbelts and the rearview mirror was refinished to restore the auto-dimming capability.

The 3.2-liter inline 6-cylinder engine sends 315 HP stock to the rear wheels through a ZF 5-speed manual transaxle with a factory-equipped limited-slip differential (3.15) allowing for a 0-60 time of approximately 5 seconds. Compared to the standard Z3, the M Coupe is equipped with a firmer suspension, thicker anti-roll bars, more robust semi-trailing arms, and a strengthened subframe. The seller adds that a Dinan Stage 1 tune was installed under previous ownership. The CARFAX report shows a total of 20 service history entries while other noteworthy service and modifications are said to include the following:
