The finance office is where dealerships make much of their profit — and where buyers who did hours of research on the car spend ten minutes on the money. This guide levels that up.
How does dealer finance actually work?
Dealers arrange finance through their panel and are typically paid for it — commonly via a margin built into the interest rate you're offered. The convenience is real; so is the cost. The rate on the glossy brochure ("2.9% finance!") is often tied to a higher drive-away price or restricted to specific stock — the discount you didn't get is the finance cost.
The fix is sequencing: sort finance first, then shop. Pre-approved buyers negotiate on the one number that matters — the drive-away price — and can't be upsold in the finance office, because they don't need it.
Which structure fits you?
| You are... | Best-fit structure | Why |
|---|---|---|
| Business owner / ABN holder, vehicle mostly for work | Chattel mortgage | Own it day one; interest & depreciation generally deductible |
| Employee with salary packaging | Novated lease | Pre-tax repayments; EVs currently FBT-exempt |
| Private buyer | Consumer car loan | Straightforward; secured rates beat unsecured |
| Cash-rich with a mortgage | Maybe don't finance the car at all... | ...or do — see below |
The offset trick: if paying cash for the car would drain an offset account against your home loan, compare carefully. Home-loan interest saved by keeping cash in the offset often exceeds car-loan interest paid — meaning financing the car and leaving your cash offsetting can be the cheaper move overall. We run this comparison for clients routinely; the answer isn't always intuitive.
What about balloons?
A balloon (residual) leaves a lump sum to the end of the loan, lowering monthly repayments. Sensible when you'll sell or upgrade the vehicle at term's end; risky when it's oversized relative to the car's future value. Rule of thumb: the balloon should comfortably undercut the car's expected worth at that date. We set balloons conservatively and diarise them so they never arrive as a surprise.
Buying used or private — what changes?
Lenders finance used vehicles and private sales readily, with two standard conditions: the car is usually under 10–12 years old at the end of the term and valued above $10,000. Private sales add checks — verifying the seller owns the car, confirming no finance is owed on it (or paying it out at settlement) — all of which a broker handles. Same-day approvals still apply to most deals.
The 60-second checklist before you sign anything
- Get pre-approved before visiting the dealership.
- Negotiate the drive-away price only — never the monthly repayment.
- Compare the dealer's finance offer (if any) against your pre-approval on total cost, not the sticker rate.
- Check the balloon against realistic resale value.
- Business use? Confirm the structure with your accountant before settlement, not after.
