Used 2018 BMW M3 CS Sedan Trims Comparison

Much like the standard M3, the M3 CS comes equipped with an exclusive exterior fascia and interior trim package. A staggered tire setup — 19-inch front and 20-inch rear — comes with summer performance tires. You also get an adaptive suspension, and an electrically adjustable rear differential sends power evenly to both rear wheels.

But the M3 CS isn't a stripped-out sport sedan. Standard equipment includes a surround-sound audio system, navigation, power-adjustable front seats, Apple CarPlay connectivity, and BMW's ConnectedDrive and Remote Services systems that integrate your smartphone to the car.

Safety-oriented standard features include adaptive cruise control, LED headlights, automatic windshield wipers, auto-dimming interior and exterior mirrors, and a rearview camera.

The M3 CS is light on options. The Executive package includes rear power sunshade and manual side window sunshades, ultrasonic parking sensors, adaptive LED headlights with automatic high-beam activation, a head-up display and speed-limit sign recognition.

The only stand-alone options are for carbon-ceramic brakes and two special-order paint colors: Frozen Dark Blue II and Lime Rock Grey.
