The True Cost of Owning a Supercar in Australia

The sticker price of a supercar is the starting point, not the finish line. Once you add on-road costs, annual servicing, tyres, insurance, fuel, and the slow drip of depreciation, the real cost of ownership is a very different number. This is a realistic breakdown, using Ferrari and Porsche as examples, of what a supercar actually costs to own in Australia.

Purchase Price and On-Road Costs

The advertised price of a new supercar in Australia includes GST and Luxury Car Tax (LCT). What it does not include are the on-road costs you pay before the car is registered in your name.

Take two benchmark examples: the Ferrari Roma, which launched in Australia at $409,888 before on-road costs in July 2020 (GoAuto), and the Porsche 911 GT3 RS, which Porsche Australia launched in August 2022 at $500,200 before on-road costs (Porsche Newsroom Australia). Porsche Australia no longer lists the GT3 RS on its 911 page (checked 25 October 2026), so that is a launch price, not a current one.

Stamp Duty

Stamp duty is levied by state governments and calculated on the vehicle’s market value. For a $380,000 vehicle in Victoria, the total stamp duty is in the range of $30,000 to $34,000. In New South Wales, the tiered structure produces roughly $16,750 on the same vehicle. In Western Australia, the flat 6.5 per cent rate produces $24,700.

Stamp duty alone can add $15,000 to $34,000 depending on your state. If you are buying between states, or considering moving, this difference is worth factoring in.

Registration and CTP

Registration and CTP combined: approximately $1,000 to $2,000 per year.

Delivery Charges

Most new supercar purchases include a dealer delivery charge, typically $2,000 to $5,000.

Annual Servicing

This is where supercar running costs separate from normal car costs – dramatically.

Ferrari’s 7-Year Genuine Maintenance program is one of the most significant ownership benefits in the prestige segment. As at October 2026, Ferrari’s 7-Year Genuine Maintenance program covers scheduled servicing for the first seven years of a Ferrari’s service life, with original parts and checks by technicians trained at Ferrari’s Training Centre in Maranello. You can service every 20,000 km or once a year, with no mileage restriction, and the program also applies to pre-owned Ferraris bought from an official Ferrari dealer. Ferrari says the conditions may not apply to limited-edition models.

After the seven-year period ends, a standard annual inspection and oil service at a Ferrari-authorised dealer costs approximately $1,500 to $3,500. More involved services can reach $5,000 to $8,000.

Porsche does not offer an equivalent maintenance inclusion program. An annual service at a Porsche Centre will typically run $1,500 to $3,000 for a standard oil and inspection service.

Tyres

Tyre costs for supercars are significant and often underestimated.

The Ferrari Roma runs on Pirelli P Zero tyres in sizes 245/35 ZR20 front and 305/30 ZR20 rear. The Porsche 911 GT3 RS uses 275/35 R20 front and 335/30 R21 rear (Porsche). A full set of four, supplied and fitted at an Australian tyre specialist, should be budgeted at $3,500 to $6,000.

Wear rates depend heavily on driving style and track use. On public roads alone, a spirited driver might replace a full set every 18,000 to 25,000 km.

Insurance

Specialist agreed-value insurance is the appropriate cover for any supercar. Australian specialist insurers – including Shannons, Enthusiast Motor Insurance, and JUA Underwriting – offer agreed-value policies for high-value and prestige vehicles.

For a Ferrari Roma insured at $400,000 with a driver over 35 with a clean record, an agreed-value policy through a specialist insurer will typically cost $8,000 to $15,000 per year. The Porsche GT3 RS, given its more focused performance profile, is rated similarly or slightly higher.

If you plan to track your GT3 RS, you need separate track day insurance, which adds $500 to $2,000 per day.

Fuel Costs

Both the Roma and GT3 RS require premium 98 RON unleaded. Neither is economical.

At $2.10 per litre for 98 RON fuel and assuming 15,000 km per year:

• Ferrari Roma at 13 litres/100 km: approximately $4,095 per year
• Porsche 911 GT3 RS at 15 litres/100 km: approximately $4,725 per year

Depreciation

Ferraris generally hold their value better than most brands. The 7-Year Genuine Maintenance program and Ferrari’s allocation-controlled approach to production help underpin resale prices.

For budgeting purposes, assume 10 to 15 per cent depreciation over three years for a standard-usage supercar in good condition. On a Ferrari Roma at its $409,888 launch price, that is about $41,000 to $61,500 over three years, or about $13,700 to $20,500 a year.

Annual Cost Summary

Here is a realistic annual cost estimate for a Ferrari Roma across three ownership scenarios after the seven-year maintenance program has concluded:

• Conservative (low km, no track): approximately $26,000 per year
• Moderate (average use): approximately $38,000 per year
• High (high km, track days): approximately $54,000 per year

For a Porsche 911 GT3 RS:

• Conservative: approximately $30,500 per year
• Moderate: approximately $45,000 per year
• High: approximately $63,500 per year

These figures exclude the initial purchase year’s stamp duty and on-road costs, which are one-off.

They also leave out unplanned repairs. The maintenance program above covers scheduled servicing only, so once the maker’s warranty ends, a failed gearbox or clutch is a bill on top of these totals. Keep a repair reserve alongside the annual figure.

The Honest Conclusion

Owning a supercar in Australia costs significantly more than the purchase price suggests. Once you account for stamp duty, specialist insurance, tyre replacement, ongoing servicing, and depreciation, a realistic annual cost of ownership for a car like a Ferrari Roma or Porsche 911 GT3 RS sits between $30,000 and $55,000 per year depending on usage.

That is not a reason not to buy one. It is simply the reality of supercar ownership done properly. Understanding the full cost upfront means no surprises once the keys are in your hand.
