Verdict
These two sedans sit worlds apart in budget and intent. The RM846,800 BMW M3 costs RM553,912 more, but brings 503 hp, 650 Nm, all-wheel drive and a 3.5-second 0-100 km/h time; the Mercedes-Benz C-Class makes 201 hp and 300 Nm, reaching 100 km/h in 7.3 seconds. For Malaysian running costs, the C-Class is far easier to justify: 6.6 L/100 km, 151 g/km and RM90 annual road tax versus 10.1 L/100 km, 230 g/km and RM2,113. The M3 buys outright pace, larger 480-litre boot and performance hardware; the C-Class is the rational executive sedan.
M3
Pick the BMW M3 if 503 hp, 650 Nm, all-wheel drive and a 3.5-second 0-100 km/h sprint matter more than the RM553,912 price gap and higher running costs.
C-Class
Pick the Mercedes-Benz C-Class if you want a RM292,888 compact executive sedan with 6.6 L/100 km economy, RM90 road tax and stronger lane-keeping intervention.
