The "always buy used" advice was true 10 years ago. In 2026, the maths are more nuanced. New car prices have increased, but so have used car prices. And new cars now come with safety tech, warranties, and finance rates that change the equation.
Quick Answer
- Buy new if: You want full warranty coverage, latest safety tech, can get 0-2% finance, plan to keep it 5+ years, or want a hybrid/EV (used market is thin)
- Buy used (1-3 years old) if: You want to dodge first-year depreciation, don't mind missing the latest features, and can verify service history
- Buy used (5+ years old) if: Budget is tight, you're mechanically savvy, or it's a second car that doesn't need to be perfect
The Depreciation Maths
This is the single biggest factor. A new car loses 15-25% of its value in year one. A 3-year-old car has already absorbed this hit.
| Scenario | Buy Price | Value at 5yr | Depreciation |
|---|---|---|---|
| New RAV4 Hybrid ($49k) | $49,000 | $27,000 | $22,000 |
| 3yr old RAV4 Hybrid ($35k) | $35,000 | $20,000 | $15,000 |
| 5yr old RAV4 Hybrid ($27k) | $27,000 | $15,000 | $12,000 |
The 3-year-old car saves $7,000 in depreciation over the same 5-year ownership period. But there's more to the story.
What New Gets You That Used Doesn't
| Factor | New | Used (3yr) | Used (5yr+) |
|---|---|---|---|
| Factory Warranty | Full 5-7yr | 2-4yr remaining | None |
| Latest Safety Tech | Current gen | Previous gen | Older gen |
| Finance Rate | 0-4% | 5-8% | 7-12% |
| Stamp Duty | Higher | Lower | Lowest |
| Known History | 100% | Check needed | Higher risk |
| Hybrid/EV Availability | Full range | Limited | Very limited |
The Finance Rate Trap
This is the factor most people miss. New car finance rates in 2026 can be as low as 0-2% from manufacturer finance (Toyota, Kia, Hyundai all offer promotional rates). Used car loans typically run 6-9%.
| Loan | Amount | Rate | 5yr Interest | Total Paid |
|---|---|---|---|---|
| New car (1.9%) | $45,000 | 1.9% | $2,200 | $47,200 |
| Used car (7.5%) | $32,000 | 7.5% | $6,400 | $38,400 |
The used car is $13k cheaper to buy. but $4,200 of that saving is eaten by higher interest. The real gap is $8,800, not $13,000. And the new car has 5 years of warranty vs 2 years remaining on the used car.
Safety: The Generational Leap
A 2026 car has safety tech that a 2021 car doesn't:
- Centre airbag. prevents head injuries between front occupants in side impacts
- Intersection AEB. brakes for cross-traffic when turning
- Rear seat monitoring. alerts if a child is left in the car
- Emergency steering assist. helps steer around obstacles
- Updated crash structures. new ANCAP protocols are stricter every year
A 5-star rating from 2021 is NOT the same as a 5-star from 2026. The standards get harder every year. If safety is a priority. especially with kids. new is meaningfully safer.
When Used is the Clear Winner
- Second car. if it's a weekend/errands car, a $15-20k used Toyota is the most rational choice
- First car for a P-plater. a $10-15k used Corolla or Mazda3 with 5 stars is safer and cheaper than a new $20k budget car
- Short-term need. buying for 1-2 years? Used loses less in depreciation
- Toyota/Mazda. these brands are so reliable that a 5-year-old example with service history is still extremely low-risk
When New is the Clear Winner
- Hybrid/EV. the used hybrid market is thin and overpriced. New hybrids are better value right now
- 0% finance available. if the manufacturer offers 0%, the maths always favour new
- High-km driver. if you drive 25,000+ km/year, warranty coverage for 5-7 years is worth a lot
- Family car. latest safety tech, full warranty, and no hidden history. Peace of mind has value
Used Car Buying Checklist
If you go used, protect yourself:
- PPSR check ($2). confirms no finance owing, not stolen, not written off
- Full service history. worth $2,000-5,000 at resale. Walk away without it
- Independent pre-purchase inspection ($250-350). non-negotiable for any car over $10k
- Check recall status. free at productsafety.gov.au
- Test drive for 30+ minutes. include highway, hills, and speed bumps. Short test drives hide problems
The Verdict
In 2026, the old "always buy used" advice doesn't hold. New cars with low-rate finance, full warranties, and latest safety tech can be cheaper over 5 years than a used car with high-rate finance and no warranty. Run the numbers for YOUR situation. the answer depends on the specific cars, finance rates, and how long you'll keep it.
