Used Car Guides
Structured advice for evaluating, purchasing, and owning used vehicles in the Australian market. Practical frameworks backed by market data.
Pre-Purchase Inspection Checklist
Before committing to a used vehicle purchase — whether private sale or dealer — work through this structured inspection framework. Print or save this list and use it on-site.
Documentation
- Verify registration status via state transport authority (REVS/PPSR check)
- Confirm service history — logbook stamps, receipts, or digital records
- Check for outstanding finance encumbrances (PPSR search)
- Review number of previous owners and registration history
- Confirm compliance plate and build date match advertised model year
Exterior & Structure
- Panel gap consistency — uneven gaps suggest accident repair
- Paint colour match across all panels under different lighting
- Check boot floor, spare tyre well, and door sills for rust or repair signs
- Tyre tread depth (minimum 1.5 mm legal, recommend 3 mm+)
- Windscreen chips, wiper condition, and all light functionality
Mechanical
- Cold start — listen for knocking, rattling, or excessive smoke
- Engine oil level and condition (milky oil suggests head gasket issues)
- Transmission shifts smoothly without hesitation or jerking
- Brake pedal firmness and steering alignment on test drive
- No warning lights on dashboard during operation
Depreciation Explained
Depreciation is the single largest cost of car ownership, yet it is often overlooked during purchase decisions. In Australia, new vehicles typically lose 15–25% of value in the first year and 40–55% over three years.
Segments that hold value well: Toyota Hilux and LandCruiser (commercial demand), Mazda CX-5 and Toyota RAV4 (strong resale market), and selected European models with cult followings.
Segments with steep depreciation: Large sedans (Commodore, Falcon successors), luxury imports beyond warranty, and early-adoption EVs facing rapid technology change.
Buying a 2–3 year old vehicle often captures the steepest depreciation curve while retaining modern safety features and remaining factory warranty.
Reliability Factors
Reliability varies significantly by make, model, and generation. When evaluating a used vehicle, consider:
- Model-specific issues: Research known faults for the exact generation (e.g., timing chain wear, DSG mechatronic failures, CVT overheating).
- Service history compliance: A well-maintained vehicle with complete records typically outperforms a low-kilometre car with no history.
- Australian conditions: Heat, dust, and towing loads affect wear rates differently than overseas reliability data suggests.
- Parts availability: Popular models have cheaper, readily available parts. Obscure imports may face long wait times.
Cost of Ownership Breakdown
Annual ownership costs for a typical $30,000 used vehicle in Australia:
| Cost Category | Annual Estimate |
|---|---|
| Compulsory third party / comprehensive insurance | $1,200 – $2,500 |
| Registration & CTP | $600 – $1,200 |
| Fuel (15,000 km @ 8L/100km) | $1,800 – $2,400 |
| Servicing & maintenance | $800 – $1,800 |
| Tyres (amortised) | $300 – $600 |
| Depreciation | $2,000 – $4,500 |
| Total estimated annual cost | $6,700 – $13,000 |
Common Buying Mistakes
- Skipping the PPSR check — purchasing a vehicle with outstanding finance can result in repossession.
- Buying on emotion — urgency and attachment lead to overlooked mechanical issues.
- Ignoring total cost of ownership — a cheap purchase price with high running costs is not a bargain.
- Not test driving long enough — 15 minutes on varied roads reveals more than a driveway idle.
- Assuming dealer warranty covers everything — statutory warranty has exclusions; read the terms.
- Overlooking insurance quotes — premiums vary dramatically by model, age, and postcode.
