First Car Buying Guide Australia: New vs Used, Finance, and What to Check (2026)

The new vs used decision is primarily about depreciation versus warranty certainty:

• New car depreciation: A new car loses approximately 15–20% of its value in the first year and 50–60% over three years. Buying new means absorbing the steepest part of the depreciation curve. For a $30,000 new car, you might pay $18,000–$20,000 for the same vehicle three years and 50,000km later.
• New car advantages: Full manufacturer warranty (typically 5–7 years), no hidden history, known service record, current safety features and technology, and often manufacturer finance deals. Suitable when reliability certainty is paramount and you plan to keep the vehicle long-term.
• Used car sweet spot: Vehicles that are 3–5 years old with 40,000–80,000km have absorbed most of their depreciation but still have significant usable life and often remaining manufacturer warranty. This is typically the best value proposition for a first car.
• Avoiding the used car risk zone: Very high mileage (200,000km+) vehicles, private sales with no service records, cars from non-PPSR-clear checks (see below), or suspiciously cheap vehicles from unknown sellers. These risks are disproportionate for first-time buyers without mechanical knowledge.

Do these checks before any physical inspection:

• PPSR check: The Personal Property Securities Register (ppsr.gov.au) check ($2) reveals whether a vehicle has money owing on it (finance encumbrance), has been written off, reported stolen, or has other security interests. Never buy a car without a clear PPSR check - you can inherit the seller's debt.
• VIN and compliance plate check: Verify the Vehicle Identification Number on the dashboard matches the compliance plate under the bonnet and the registration papers. Mismatches indicate potential fraud or rebirthing (illegal modification of a written-off vehicle).
• Service history: Ask for the full service log - ideally stamped by a licensed repairer. Gaps in service history for a higher-mileage vehicle are a yellow flag. Check whether services have been conducted at the manufacturer's recommended intervals.
• REVs check (state-based): Some states maintain separate registers equivalent to PPSR. Victoria's VicRoads check, for example, provides registration and compliance information.

A systematic physical inspection catches most major issues before purchase:

• Panel gaps and paint: Walk around the car looking for uneven panel gaps and paint colour or texture differences between panels - indicators of previous accident repair. Use a paint thickness gauge app or hire a pre-purchase inspector.
• Tyres: Check tread depth (legal minimum 1.5mm; safe minimum 3mm) and whether wear is even across the tyre width. Uneven wear suggests alignment or suspension issues.
• Under the bonnet: Check engine oil on the dipstick (dark black = worn, milky = water contamination = head gasket concern). Check coolant level and colour. Look for oil or coolant leaks on the engine block.
• Under the car: Look for rust on the chassis, floor pans, and subframe (more relevant for older vehicles). Check for recent undercoating that could mask rust.
• Test drive: Listen for unusual engine or gearbox noises. Test all brakes at different speeds. Check air conditioning, all windows, all lights, infotainment, and Bluetooth. Ensure the car drives straight without pulling.
• Pre-purchase inspection: For any used car over $10,000, a pre-purchase mechanical inspection by a qualified mechanic ($150–$300) is worth every cent. The NRMA, RAA, RACV, and equivalent state motoring clubs offer this service.

Most car purchases involve finance - understanding the terms prevents expensive mistakes:

• Comparison rate vs advertised rate: Lenders advertise low headline rates but must also display the comparison rate (which includes fees). The comparison rate is the true cost of the loan. Compare comparison rates across lenders.
• Dealer finance vs bank finance: Dealers offer convenience but dealers earn commissions on finance products. Get a pre-approval from your bank or a comparison site (Canstar, RateCity) before visiting a dealership - this gives you a benchmark and negotiating power.
• Balloon payments: Some car loans offer lower monthly repayments in exchange for a large 'balloon' payment at the end (typically 20–30% of the purchase price). This defers rather than eliminates the cost and means you owe more than the car is worth if you want to exit the loan early.
• Loan term: Car loans of 5–7 years reduce monthly repayments but significantly increase total interest paid. A $20,000 loan at 8% over 5 years costs $4,332 in interest; over 7 years it costs $6,119. Match the loan term to how long you plan to keep the car.
• CTP and comprehensive insurance: Compulsory Third Party (CTP) insurance is mandatory and included in registration in most states. Comprehensive car insurance - covering your own vehicle - is separate and essential for a financed vehicle (most lenders require it). Compare premiums at comparison sites before purchase.

Car prices are negotiable - both new and used:

• Research the market: Use CarsGuide and carsales.com.au to understand what equivalent vehicles (same make, model, year, mileage, condition) are selling for in your area. Print or screenshot several comparable listings.
• Start below your target: Offer 5–10% below the listed price and justify it with specifics (comparable listings, inspection findings, any issues found). Be polite and specific - a lowball offer without reasoning is easily dismissed.
• On new cars, negotiate on-road costs and extras: Dealers have limited flexibility on the drive-away price for popular models but can often include floor mats, window tinting, extended warranty, first service, or registration costs. These have real value.
• End of month and end of financial year: Dealers have monthly and EOFY sales targets. Visiting in the last few days of June or the last few days of a calendar month typically produces the best price flexibility.
• Walk away: If you cannot reach agreement, leaving is your most powerful negotiating tool. Dealers frequently call back with improved offers.
