The real cost of owning a C 300 Sedan in Australia

The better-equipped C 300 generally sits above the Luxury Car Tax threshold, and its higher value flows through to insurance, stamp duty and depreciation.

• A purchase price that usually sits above the Luxury Car Tax threshold
• Higher stamp duty and insurance than the C 200
• Separate servicing, registration and CTP costs
• Luxury-sedan depreciation over the first three years

The C 300 is typically priced above the Luxury Car Tax threshold, so a portion of the price attracts the 33 per cent LCT.

Subscription pricing

Premier Drive offers flexible 3, 6, 9 and 12-month subscriptions for the C 300 Sedan. Every plan is an all-inclusive weekly payment covering insurance, servicing, registration, telematics and roadside assistance, with 385 km per week included.

Why a subscription can beat owning the C 300 Sedan

With a subscription the C 300 is delivered fully maintained and insured for one weekly figure, and you stay free to change model when your needs evolve.

• One weekly payment covers the car, comprehensive insurance, servicing, registration and CTP, telematics and roadside assistance.
• Predictable weekly payment, so you can plan cash flow without unexpected running-cost surprises.
• Zero residual-value risk, so you never have to tip money in at resale or time a private sale.
• Freedom to change to a different Mercedes-Benz as your needs change, rather than being locked in for years.

Australian tax and regulation notes

Buying a vehicle like the C 300 Sedan in Australia brings several costs that rarely appear on the advertised price. Understanding them makes the value of an all-inclusive subscription clearer.

• Luxury Car Tax (LCT) of 33 per cent applies to the value above the LCT threshold. For the 2025-26 financial year the threshold is around $80,567 for most vehicles and around $91,387 for fuel-efficient vehicles, and it is updated annually by the ATO.
• Stamp duty is charged on purchase and varies by state, with higher rates applied to higher-value and luxury vehicles.
• If you buy through a business, the ATO car limit (around $69,674 for 2025-26) caps the depreciation and GST you can claim.
• Comprehensive insurance, scheduled servicing, registration and CTP are all paid separately when you own, and they tend to rise over time.

These figures are general in nature, change over time, and are not financial or tax advice. Confirm current thresholds with the ATO and speak with your accountant about your circumstances.

In short, the C 300 Sedan suits drivers who want a more powerful, better-equipped executive sedan without the ownership commitment. If that sounds like you, our concierge team can confirm current pricing and availability and have your chosen model delivered.
