Should you trade in your car at a dealership or sell it privately? An honest breakdown of price difference, convenience, and tax implications.
On average, a dealer trade-in offers 15–25% less than the open market value of your car. On a $25,000 vehicle, that's $3,750–$6,250. Dealers need margin to recondition and resell the car.
But private sales require real effort: listing, communication, test drives, negotiations, and waiting for payment. For sellers who are time-poor or selling an older vehicle, the convenience of a trade-in can be worth the gap.
A third option — direct car buyers like Sold Fast — sits in the middle: typically 5–12% below private sale price, but with the convenience of a trade-in (we come to you, pay on the spot, no waiting).
One tax implication often overlooked: when you trade in at a dealership, stamp duty on your new car purchase is calculated on the price after the trade-in deduction — not the full purchase price. This can save $200–$600 in stamp duty depending on your state.
This benefit doesn't apply when selling privately or to a direct car buyer. It's a legitimate financial reason to favour a trade-in if you're spending over $30,000 on a new vehicle at the same time.
Typically 15–25% less than private market value. Dealers factor in reconditioning costs, wholesale margins, and time-in-stock risk.
In most Australian states yes — stamp duty on the new purchase is calculated on the net price (after trade-in deduction). This can save $200–$600 depending on state rates and the vehicle value.
Selling privately might seem like the obvious choice for maximum return — but the real costs, risks, and time involved often tell a different story. Here's an honest comparison.
Selling your car for the best possible price isn't just about luck — it's about strategy. This guide covers what actually moves the needle when selling a car in Australia.
Most private car sales in Australia are GST-free — but there are exceptions. This guide explains when GST applies and what it means for sellers.
