When it comes to buying a car in Australia, two loan types dominate: the secured car loan and the personal loan. Both can get you behind the wheel, but they work very differently — and choosing the wrong one can cost you thousands over the life of the loan. Here's the complete comparison.

💡 Drive Select Finance offers both secured car loans and personal loans through 30+ lenders. Our brokers recommend the right product for your situation — free service, no credit impact.

What Is a Secured Car Loan?

A secured car loan uses the vehicle as collateral. The lender has a registered interest over the car — meaning if you default, they can repossess and sell it to recover the debt. Because this reduces the lender's risk, secured car loans typically offer lower interest rates than unsecured alternatives.

Most car loans in Australia are secured. They're structured specifically for vehicle purchases with terms of 1–7 years and amounts from $8,000 to $150,000+.

What Is a Personal Loan for a Car?

A personal loan is an unsecured loan — meaning no asset is used as security. The lender relies solely on your creditworthiness and income to decide whether to lend. Because there's no security, rates are typically higher than secured car loans.

Personal loans can be used for almost any purpose, including buying a car, which makes them flexible — but this flexibility comes at a cost.

Interest Rate Comparison

This is where the difference is most stark:

  • Secured car loan: From 5.68% p.a. for excellent credit — typically 6–12% p.a. for most borrowers
  • Unsecured personal loan: Typically 8–20% p.a. for the same borrower profile

On a $30,000 loan over 5 years, the difference between 7% (secured) and 13% (unsecured) is approximately $5,000 in additional interest. For most buyers, a secured car loan is clearly the better financial choice.

When a Personal Loan Makes Sense for a Car

Despite the higher rates, there are genuine scenarios where a personal loan is the smarter or only option:

Older Vehicles

Most lenders won't offer secured car loans on vehicles over 12–15 years old at the end of the loan term. If you're buying an older vehicle, a personal loan may be your only choice.

High-Odometer Vehicles

Vehicles with 150,000km+ may not qualify for a secured car loan. Personal loans aren't asset-dependent, so odometer doesn't matter.

Small Loan Amounts

For amounts under $8,000–$10,000, some lenders won't offer secured car loans. Personal loans start from $2,000–$3,000 at many lenders.

You Want Flexibility to Pay Off Early

Some personal loans offer more flexibility on early repayment without break fees. Check terms carefully — some secured car loans have similar flexibility.

🔑 Key Decision Point

If the vehicle is under 12 years old and in reasonable condition, a secured car loan will almost certainly save you money. If the vehicle is older, higher mileage, or the amount is very small — explore personal loan options. A broker can assess both simultaneously.

Side-by-Side Comparison

  • Interest rates: Secured car loan wins (lower rates)
  • Approval speed: Personal loan can be slightly faster (no vehicle valuation)
  • Flexibility: Personal loan (any vehicle, any age)
  • Maximum amount: Secured car loan (higher limits)
  • Tax benefits (business use): Secured car loan / chattel mortgage (not personal loans)
  • Total cost: Secured car loan wins

Can I Use a Personal Loan for a Private Sale Car?

Yes — and unlike secured car loans, there's no need for a PPSR check or direct lender-to-seller payment process. For private sales of older vehicles, personal loans can actually be a simpler path.

That said, for private sale purchases of newer vehicles, secured car loans are still preferred for their lower cost. Your broker will recommend the most practical option for your specific purchase.

What About Buy-Now-Pay-Later for a Car?

BNPL products are not suitable for vehicle purchases of any meaningful amount. They cap out at $2,000–$5,000 and carry very high effective interest rates. Avoid using BNPL for car purchases.

Which Should You Choose?

For most car buyers in Australia, a secured car loan through a broker is the optimal choice — lower rates, higher limits, and structured repayments that clear the debt within a defined term.

A personal loan is best reserved for older vehicles, smaller amounts, or specific scenarios where a secured loan isn't available. Speak with one of our brokers — we compare both product types and recommend what's genuinely best for your situation.
