It's one of the most straightforward decisions in car finance — and the one people overthink the most. A secured loan uses the car as collateral and costs you less. Here's the plain version.
This is one of the most straightforward decisions in car finance — but it's the one people overthink the most. Here's the plain version.
Everything about secured vs unsecured flows from a single distinction: whether the lender has a claim on the car.
Secured car loan: The lender registers a security interest over the car on the PPSR (Personal Property Securities Register). If you stop making repayments, the lender can repossess the vehicle and sell it to recover the debt. Because the lender has this safety net, they charge a lower interest rate.
Unsecured car loan (personal loan): No security. The lender lends based purely on your income and credit profile. If you default, the lender can pursue the debt through standard debt recovery (not repossession of the car specifically). Because the lender carries more risk, you pay a higher rate.
That's it. Everything else flows from this distinction.
The headline is the rate gap. On a typical loan, that gap is thousands of dollars in extra interest.
| Factor | Secured car loan | Unsecured car loan |
|---|---|---|
| Average rate (mid-2026) | ~7.4% p.a. | ~11.8% p.a. |
| Rate range | 5.7% – 10% p.a. | 9.5% – 15%+ p.a. |
| Monthly repayment on $30,000 over 5 years | ~$600 (at 7.4%) | ~$668 (at 11.8%) |
| Total interest on $30,000 over 5 years | ~$5,990 | ~$10,050 |
| Total cost difference | — | ~$4,060 more |
| Vehicle age restrictions | Yes — typically under 7–12 years old at end of term | No restrictions |
| Lender's claim on the car | Yes — registered on PPSR until loan is repaid | None |
| Can you sell the car during the loan? | Yes, but must pay out the finance first (or transfer with lender approval) | Yes — no restrictions |
| Best for | Most buyers purchasing a car under ~10 years old | Older cars, imports, classics, or buyers who want no lender claim |

The $4,060 difference on a $30,000 loan is real money. On a $40,000 loan, the gap widens to approximately $5,400. This is why secured is the default recommendation for any car that qualifies.
Almost always, if the car qualifies. There's no scenario where an unsecured loan beats secured on a car that qualifies for it.
Almost always, if the car qualifies. If the car you're buying meets the lender's age requirements (typically under 7–12 years old at the end of the loan term, depending on the lender), a secured loan will be cheaper. There's no scenario where an unsecured loan gives you a better rate on a car that qualifies for secured finance.
Specifically, choose secured when:
Usually because the car doesn't qualify for secured finance — but there are a few other situations where it's the better fit.
When the car doesn't qualify for secured finance. This is the most common reason. If you're buying a 12-year-old car for $8,000, most lenders won't accept it as security because the resale value at the end of a 3–5 year term is too low for recovery.
Also consider unsecured when:
For borrowers with credit issues, secured loans are usually easier to get approved for — because the lender has a fallback.
For borrowers with credit issues, secured loans are usually easier to get approved for — because the lender has the car as a fallback. The security reduces the lender's risk, which means they're more willing to approve applicants who might be declined for unsecured lending.
If your credit is impaired and the car qualifies for secured finance, a secured loan gives you more lender options and a better rate than unsecured. Car loans for bad credit — your options explained.
This example illustrates the practical difference. Individual outcomes depend on your specific circumstances.

Not directly — you'd need to refinance. If you took an unsecured loan and the car qualifies for secured finance, you can refinance into a secured loan to access a lower rate. This involves paying out the existing loan and taking a new one, so factor in any early repayment fees. Car loan refinancing — when it makes sense.
No. You own the car. The lender holds a registered security interest on the PPSR, which gives them the right to repossess if you default. Once the loan is fully repaid, the security is removed. It's the same concept as a home mortgage — you own the house, the bank holds security over it.
Your insurance pays the market value. If the insurance payout covers the outstanding loan balance, the lender is repaid and any surplus goes to you. If the payout is less than the balance (because the car depreciated faster than you paid down the loan), you owe the difference. Gap insurance can cover this shortfall.
Some secured loans include a PPSR registration fee ($6–$8) and a de-registration fee at the end. These are minimal. The interest savings of secured vs unsecured far outweigh any small fee differences.
Yes. The lender will require a PPSR check on the vehicle (to confirm it's free of existing finance) and may require an independent valuation. Your broker handles this process.
For most buyers, secured is the cheaper, smarter choice — but the right answer depends on your car and your situation. Talk to the Novara team and we'll compare both options for you in minutes, with no cost and no obligation.
