Dealer or Private Seller? Which Is Actually Better for Your Next Car?

The same used car can carry two very different price tags. On a dealer's lot it might be advertised at $34,990 drive away. Parked in a driveway two suburbs over, with a handwritten sign in the window, a near identical one could be listed for a few thousand less.

So is the private sale the smarter buy? Sometimes. But that gap in price is not free money. It is roughly what you pay for legal protections, paperwork and a business that has to answer for the car after you drive it home.

This guide breaks down what you actually get, and give up, with each option in Australia, so you can decide whether the saving is worth it for you.

Quick answer: buy from a licensed dealer if you want consumer guarantees, a statutory warranty (on most cars under 10 years old), a guaranteed clear title and an easy trade in. Buy privately if you are confident checking a car yourself, the saving is meaningful, and you do a $2 PPSR search and an independent inspection before paying a cent.

Price: how much cheaper is a private sale really?

Private sellers usually ask less because they have no overheads. A dealer has to pay for the land, the staff, reconditioning, detailing, a statutory warranty and a profit margin, and all of that ends up in the sticker. A private seller just wants a fair price and a quick sale.

Across mainstream used cars, the gap is commonly somewhere between a few hundred dollars on a cheap runabout and several thousand on a late model SUV or ute..

• Dealer prices are often drive away. A used car from a dealer is usually advertised with the registration transfer and stamp duty sorted. With a private sale you arrange the transfer yourself and pay the stamp duty on top of the agreed price.
• Private prices are negotiable, but so are dealer prices. Dealers have more room on cars that have been in stock for 60 days or more, and on older trade ins they would rather not keep.
• Reconditioning has value. A dealer car has usually been serviced, detailed and had worn tyres or brakes replaced. A private car may need some of that soon after you buy it, so budget for it.

Statutory warranty and cooling off: it depends on your state

This is where dealers earn their margin. Every state sets its own rules for licensed motor dealers, and none of them apply to a private sale. The main ones look like this:

• New South Wales: a dealer guarantee of 3 months or 5,000 km (whichever comes first) on cars under 10 years old with less than 160,000 km. There is a cooling off period until 5pm the next business day, but only when the car is bought with finance arranged through the dealer. Cancelling costs $250 or 2 per cent of the price, whichever is less.
• Victoria: a statutory warranty of 3 months or 5,000 km on cars not more than 10 years old with under 160,000 km. You get three clear business days to cool off after signing, unless you take delivery first. A trader can keep $100 or 1 per cent of the price (whichever is greater) on a used car, or $400 or 2 per cent on a new one.
• Queensland: a "class A" warranty of 3 months or 5,000 km on cars under 160,000 km and no more than 10 years old, and a "class B" warranty of 1 month or 1,000 km on older or higher kilometre cars. The cooling off period is 1 business day.
• Western Australia: on cars priced at $4,000 or more, 3 months or 5,000 km for cars up to 10 years old and 150,000 km, or 1 month or 1,500 km for cars up to 12 years and 180,000 km.
• South Australia: the dealer's duty to repair runs 2 months or 3,000 km on cars sold for $3,001 to $6,000, and 3 months or 5,000 km above $6,000, with no duty to repair on cars first registered more than 15 years ago or with over 200,000 km. Since September 2025 buyers can no longer waive it, and it covers the main battery in hybrids and EVs.

Tasmania, the ACT and the Northern Territory have their own versions, so check your local consumer affairs or fair trading office before you sign. The statutory warranty is not a full mechanical warranty. It usually excludes wear items such as tyres, batteries and brake pads, so read the notice the dealer gives you.

Clear title: the guarantee you only miss when it is gone

When you buy from a licensed dealer, you get a guarantee of clear title. In Victoria that certifies the car is not listed as stolen or written off and that no money is owed on it. In NSW and Queensland the dealer guarantee also gives you access to a compensation fund if the dealer fails to meet its obligations and you cannot recover the loss.

That matters more than most buyers realise. If a car you bought privately turns out to have finance owing, the lender can repossess it from you, even though you paid the seller in full. With a licensed dealer, sorting out any encumbrance is their problem, not yours.

Consumer guarantees under the Australian Consumer Law

The ACCC is clear on this point. Consumer guarantees apply to new and used cars bought from a licensed dealer. The car must be of acceptable quality, which means safe, durable and free from defects for a car of its age, price and kilometres, and it must match its description.

If something goes badly wrong, that is a major failure, and you can choose a repair, a replacement or a refund. For a minor failure the dealer can choose to repair it, but if they don't do it in a reasonable time you can ask for a replacement or refund. The dealer also cannot simply send you off to the manufacturer.

Buy privately and most of this disappears. The ACCC notes that most consumer guarantees and state laws do not apply to private or auction sales. A private seller still has to give you clear title, undisturbed possession and no undisclosed debts, but there is no promise the car is of acceptable quality. If the gearbox fails a week later, it is usually your bill.

Private sale risks: finance owing, scams and write offs

Most private sales go smoothly. The ones that don't tend to fall into three traps.

• Finance owing. The car may still be security for a loan. If you buy it, the lender can repossess it.
• Write offs and stolen cars. A car may have been written off after a crash, flood or hailstorm and rebuilt. A statutory write off is not safe to drive and cannot be registered again, while a repairable write off may be back on the road after passing safety and identity checks, but it usually carries a lower resale value.
• Scams. Scamwatch warns that fake listings offer in demand cars well below market value, often with an urgent story such as a seller about to be deployed or move overseas, and ask for a deposit by bank transfer or through a fake "escrow" service. Some copy a genuine ad and simply change the price and phone number.

The fix for the first two costs $2. A PPSR search on the official Personal Property Securities Register (ppsr.gov.au) tells you whether money is owed on the car, and whether it has been reported as written off or stolen. Use the VIN from the car itself, not from the ad, and do the search on the day you pay, because a seller can take out a new loan between viewing and handover.

Never pay a deposit on a car you have not seen in person, and never pay a "seller" whose name doesn't match the registration papers and their ID.

For the mechanical side, book an independent pre purchase inspection. It usually costs a couple of hundred dollars and can save you thousands.

Trade in convenience

If you already own a car, the dealer route has another big advantage: you can trade it in on the spot. One visit, one set of paperwork, and no strangers turning up at your house.

The catch is that dealers pay wholesale for trade ins, so you will usually get less than you could selling privately. The honest way to judge it is to look at the changeover price, which is the difference between what you pay and what they give you. A big discount on the new car paired with a poor trade in offer can be worse than a small discount and a fair one.

Finance: dealer convenience vs shopping around

Dealers can arrange finance on the spot, and manufacturer finance on newer cars sometimes comes with low promotional rates. Private sellers obviously offer nothing, so you need a personal or secured car loan arranged in advance.

Either way, ASIC's Moneysmart advice is the same. Get approval in principle before you shop, compare the comparison rate (which rolls the interest rate and fees into one figure), and compare dealer finance against your own bank. Be careful with add on insurance sold with the loan. Salespeople must wait four days before selling it, you don't have to buy it, and the premium is often financed, so you pay interest on it too.

Who should buy from a dealer, and who should buy privately?

Our pick for most buyers: a licensed dealer. Consumer guarantees, a statutory warranty and a clear title guarantee are worth paying something for, especially on a car worth more than about $15,000, where one major repair could wipe out the private sale saving.

Choose a dealer if you:

• want legal protection if something goes wrong;
• are buying a car under 10 years old, where the statutory warranty applies in most states;
• have a car to trade in, or need finance arranged quickly;
• are not confident judging a car's mechanical condition.

Choose a private sale if you:

• are buying an older or cheaper car where dealer warranties shrink or disappear anyway;
• are comfortable organising a PPSR check, an independent inspection and the rego transfer;
• have found a well documented car with full service history and a seller you can verify;
• are getting a saving big enough to cover a surprise repair bill.

Frequently asked questions

Do I get a warranty when I buy a car privately?

No statutory warranty applies to private sales, and most Australian Consumer Law guarantees don't either. The only exception is any balance of the manufacturer's warranty, which usually transfers to the next owner.

How much does a PPSR check cost?

A self service online search costs $2, or $7 through the assisted phone service. It shows whether money is owed on the car and whether it has been reported as written off or stolen.

Can I cool off after buying a used car?

Only from a licensed dealer, and the rules vary. Victoria gives three clear business days, Queensland gives one business day, and NSW gives until 5pm the next business day but only with dealer arranged finance. There is no cooling off on a private sale.

Is a dealer always more expensive?

Not always. Dealers discount cars that have sat in stock, and their drive away price includes the transfer and stamp duty you would pay yourself on a private sale. Compare the full cost.
