Buying a car is one of the larger purchases most Australians make, and the price on the windscreen is only part of the story. Stamp duty, registration, insurance, and depreciation can move the real cost by thousands. This guide walks through the whole process — from setting a budget that includes on-road and running costs, to choosing between new, used, and demo, to negotiating on the drive-away figure and inspecting before you commit.
The most common budgeting mistake is anchoring to the purchase price and forgetting everything around it. A car's true cost has three layers: what you pay to acquire it, what you pay to keep it on the road, and what you lose to depreciation while you own it.
Before you look at a single listing, work out what you can comfortably commit each month after these are accounted for:
Our true cost of car ownership guide breaks down each of these categories with realistic figures, and the Veercal calculator totals them for a specific vehicle and hold period so you can see what a given car actually costs per year, not just per month of repayments.
If a repayment only fits your budget when you ignore insurance, fuel, and servicing, the car is too expensive — not the finance. Build the running costs into the number first, then see what purchase price is left over.
It is easy to buy for the trip you take twice a year rather than the commute you do every day. Be honest about your real usage before you fall for a body style:
There is no universally right answer — only the right answer for your budget, hold period, and appetite for risk. The trade-offs:
| Option | Strengths | Trade-offs |
|---|---|---|
| New | Full warranty, latest safety and tech, known history, finance and novated-lease friendly. | Steepest depreciation in the first years; highest purchase price. |
| Demo | Near-new condition, usually discounted off list, often still under most of the warranty. | Reduced warranty period, some kilometres already driven, limited choice of spec and colour. |
| Used | Lowest price; the first owner has absorbed the worst depreciation. | Condition and history risk; shorter or no warranty; inspection becomes essential. |
Depreciation is the hinge. A new car typically loses a meaningful share of its value in the early years; buying a two-to-three-year-old example lets someone else take that hit. Against that, a new car gives you a full warranty and a clean history. If you plan to keep the car a long time, the depreciation gap narrows in importance because you amortise it over more years.
Knowing your funding method before you walk onto a lot changes your negotiating position and stops you being steered into whatever finance the dealer earns the most commission on. The main paths in Australia are paying cash, a personal (secured) car loan, dealer finance, a finance lease or chattel mortgage (for business use), and a novated lease (for eligible employees).
Each suits a different situation, and the cheapest option on paper is not always the cheapest for you once tax, opportunity cost, and fees are included. We cover how to choose in the companion guides: guide to car finance and how to make an informed finance decision. If you are an employee earning a salary, it is worth modelling a novated lease before signing dealer finance — for eligible vehicles the tax treatment can change the comparison substantially.
This is where buyers most often compare apples with oranges. Two figures matter:
On-road costs differ by state because stamp duty schedules and registration fees are set by each state and territory. That means the same car can cost different amounts to put on the road in Victoria, New South Wales, or Queensland. Always negotiate and compare on the drive-away figure, and check the current rates with your state revenue office — our stamp duty explainer sets out how each state calculates it, including concessions that can apply to some electric vehicles.
Advertised "drive-away from" prices often apply to the base variant in a single colour. Confirm the drive-away figure for the exact variant, options, and colour you want, in writing, before you treat it as your number.
Negotiation is less about haggling theatrics and more about preparation and patience.
For a used car, this step protects you from the most expensive mistakes.
Whether buying new or used, make sure these are sorted before money changes hands:
✓ Budget covers on-road and running costs, not just the repayment
✓ You have compared on the drive-away price, not the list price
✓ Stamp duty and rego checked for your state
✓ Finance method decided in advance and compared on true total cost
✓ PPSR check and independent inspection done (used)
✓ Trade-in valued independently and negotiated separately
✓ Insurance arranged to start at handover
✓ All agreed terms in writing before any deposit
