Trade In or Sell Your Car?
The Honest Comparison

Trade-in, private sale, or direct car buyer — each option has real pros and cons. Here's what they don't tell you upfront.

When it's time to sell your car in Australia, you've got three main options: trade it in at a dealership, sell it privately through Gumtree or Facebook Marketplace, or sell directly to a car-buying service like Sold Fast. Each path has genuine advantages — and genuine costs — that are worth understanding before you decide.

This guide breaks down the real differences in money, time, effort, and safety so you can make the right call for your situation.

Sell to Sold Fast if…

Common Questions

How much less will a dealer offer for a trade-in compared to selling privately?

Typically 15–25% below what you'd get selling privately. Dealers need to cover inspection, detailing, storage, and their profit margin. On a $25,000 car, that's $3,750–$6,250 left on the table.

Is selling privately always worth the extra money?

Not always. Factor in your time (advertising, calls, test drives, negotiations), safety risks, and the possibility of the sale falling through. For many sellers, the convenience of a direct buyer is worth more than a few extra thousand dollars.

What if I still owe money on my car?

Both trade-in and Sold Fast can handle financed vehicles. We pay your lender directly and transfer any remaining equity to you. Private buyers, on the other hand, typically require you to settle the loan first — which can complicate the sale.

Can I negotiate with Sold Fast the same way I can privately?

Yes. Our offer is based on current market data and the condition of your car, and you're welcome to discuss it with us. Unlike a private sale though, there's no haggling with strangers or risk of last-minute lowballing.

Does a trade-in affect the GST on my new car purchase?

Yes — trading in can reduce the taxable amount on your new car purchase in Australia, which can save you money on stamp duty depending on your state. If this applies to your situation, speak with your dealer or accountant.
