A detailed look at how two of Australia's most popular Sedans compare on price, running costs, safety, and everyday livability.
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Price Breakdown
The BMW 5 Series starts from $114,900 before on-road costs, while the Mercedes-Benz C-Class opens at $76,900. That makes the Mercedes-Benz C-Class the more affordable entry point by $38,000.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $126,390 and $84,590 respectively.
Over 5 years, the running costs favour the BMW 5 Series by roughly $1,000 in fuel alone.

Feature Showdown
The BMW 5 Series features a 14.9-inch touchscreen, while the Mercedes-Benz C-Class gets a 11.9-inch display. Apple CarPlay and Android Auto are standard across both.
The BMW 5 Series stands out with heated front seats, power tailgate and Harman Kardon audio that you will not find on the Mercedes-Benz C-Class. The Mercedes-Benz C-Class counters with ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The BMW 5 Series uses a Petrol producing 150kW and 300Nm of torque, sent through a auto to a RWD layout. It covers the 0-100km/h sprint in 5.6 seconds.
The Mercedes-Benz C-Class responds with a Petrol making 150kW and 300Nm, paired to a automatic driving the rear wheels. It gets to 100km/h in 7.8 seconds.
Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. In the real-world sprint, the BMW 5 Series is 2.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BMW 5 Series measures 5,060mm long on a 2,995mm wheelbase, 309mm longer than the Mercedes-Benz C-Class at 4,751mm (2,865mm wheelbase). The longer wheelbase on the BMW 5 Series generally means more rear legroom.
