BMW pays for scheduled maintenance on the M3 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the C63 Sedan.

Tires and Wheels Comparison

For better traction, the M3 has larger standard tires than the C63 Sedan (F:255/40R18 & R:275/40R18 vs. F:245/40R18 & R:265/35R18). The M3 Competition Package’s tires are larger than the largest tires available on the C63 Sedan (F:265/30R20 & R:285/30R20 vs. F:245/40R18 & R:265/35R18).

The M3 Competition Package’s tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the C63 Sedan’s optional 35 series tires.
