After inspecting 1,000+ vehicles a year across NSW, our mobile mechanics see roughly 60% private sales and 35% dealer sales. The dealer cars surprise people the most.
A private NSW car is cheaper but sold "as-is" with zero warranty. A NSW dealer car costs more but comes with a statutory warranty if it qualifies, plus rights under the Australian Consumer Law. Both can hide expensive problems. The decision is not really "private vs dealer"; it is "how much protection am I paying for, and is it worth the markup".
On the same year, make, model, and km, a dealer in NSW typically charges $2,000 to $5,000 more than a private seller. A 2018 Toyota RAV4 GXL with 90,000 km sits around $24,000 to $26,000 private on Carsales and Facebook Marketplace; the same car at a dealer on Parramatta Road or in Liverpool will be $27,000 to $30,000.
That gap pays for the dealer's reconditioning, their floor plan finance, GST, and their statutory warranty obligation. Whether it is worth it depends entirely on the specific car, not on private vs dealer as a category.
Under the NSW Motor Dealers and Repairers Act, a licensed dealer must provide a statutory warranty on most used cars they sell. The car qualifies if it is:
If the car qualifies, the warranty covers 3 months or 5,000 km, whichever comes first. It covers defects that existed at the time of sale and were not disclosed.
It does not cover:
Private sellers in NSW give you none of this. A handshake and a signed receipt is the entire warranty.
We see the statutory warranty work well for engine, transmission, and electrical faults that show up within the first month. We see it work poorly when the dealer disputes whether the fault existed at sale, or when the dealer is no longer trading. The warranty is real protection, but it is not automatic; you may end up at NSW Fair Trading or NCAT to enforce it.
NSW gives you a 1-business-day cooling-off period when you buy from a licensed dealer on credit (a finance contract). You can cancel the contract; the dealer can keep $250 or 2% of the price, whichever is less.
There is no cooling-off period if you pay cash, pay by EFT, or buy privately. Once you have paid and signed, the car is yours. This is why an inspection before payment matters more than people think.
Private sales fail in predictable ways. After 1,000+ NSW inspections, these are the recurring patterns our inspectors flag:
The seller has a personal loan secured against the car. You buy it, the finance company repossesses it from your driveway in Blacktown three weeks later, and you have lost the lot. A $2 PPSR check prevents this entirely.
The car was written off after a crash, repaired, and re-registered with NSW plates. PPSR catches federal write-offs; the NSW Written-Off Vehicles Register catches state-recorded ones. Cars sold with this history are worth 30 to 50% less than equivalent clean-history cars.
More common on older Japanese imports and ex-fleet cars. The service book and the odometer disagree, or the wear on the steering wheel and pedals does not match a 60,000 km reading. Our inspectors check this on every job.
Sellers who know the car has issues will clear the codes before the test drive. The dashboard looks clean. Our scanner reads the history of fault codes, not just the current ones; cleared codes leave a trace.
If the seller will not show you stamped service book entries or workshop invoices, assume the service did not happen. We see this monthly on private sales in Western Sydney.
Catch finance owing and federal write-offs before you pay.

NSW dealers are not required to do a comprehensive mechanical check before selling, and most in-house inspections are pre-sale presentation work, not diagnostics. We have inspected dealer cars with $2,000+ in repairs needed despite a "100-point check" sticker on the windscreen.
Paint protection, fabric protection, extended warranty, window tinting. A $1,500 to $4,000 stack of add-ons added at the contract stage, after you have emotionally bought the car. You can decline all of them; they are not part of the car price.
Dealers will offer a strong trade-in valuation and recover it by holding firm on the car price; or vice versa. Negotiate the car price and the trade-in price separately. Always get a private valuation on your trade-in (Redbook, CarsGuide) before you walk in.
Dealer finance is rarely the cheapest option in NSW. A pre-approval from your bank or a broker gives you a number to negotiate against. If the dealer beats it, take it; if they do not, walk to the better rate.
Private is the right call when:
Most of our happiest customers are private buyers who paid for an inspection. The inspection cost (from $300 in Sydney) plus the $2 PPSR check is the cheapest insurance in the car-buying process.
Dealer is the right call when:
Still get an independent inspection. We inspect cars at NSW dealers every week; a reputable dealer will allow it without hesitation.
| Factor | Private seller | NSW licensed dealer |
|---|---|---|
| Price | Lowest | Highest |
| Statutory warranty | None | Yes, if car qualifies |
| Cooling-off period | None | 1 business day (finance only) |
| ACL protection | Limited | Full |
| GST included | No | Yes |
| Trade-in option | No | Yes |
| Recovery if seller disappears | Civil claim only | Fair Trading + NCAT |
| Risk of finance owed | Real (check PPSR) | Negligible |
If the car qualifies for the statutory warranty and the dealer premium is under $3,000, dealer is usually worth it. If the car is over 10 years old or over 160,000 km, the dealer's statutory warranty does not apply, so you are paying the markup for paperwork convenience only; private is the better value.
In both cases, an independent pre-purchase inspection is non-negotiable. The cars that cost our clients the most money are not the ones bought privately or from a dealer; they are the ones bought without an inspection.

Lead Mechanic, Sydney Mobile Car InspectionsOnly if you can prove they misrepresented the car (lied about km, hid known faults, sold a stolen or written-off car as clean). This usually means NCAT or the Local Court. "As-is" is otherwise final.
If the engine fault existed at the time of sale and was not disclosed, yes. If it failed due to your use after purchase, no. The dispute is almost always about which one it is; documented evidence (including a pre-purchase inspection report) helps your case.
Yes, if it has been repaired and re-registered as a "repairable write-off" and the dealer discloses the history in writing. Many do not disclose it clearly. Always check the NSW Written-Off Vehicles Register yourself.
No. A dealer car can still have hidden mechanical issues, and "certified" does not mean "inspected to a professional standard". The statutory warranty gives you recourse if things go wrong; it does not prevent things from going wrong.
Yes. We inspect dealer cars at yards across Sydney every week. A reputable dealer will allow it; a dealer who refuses is telling you something.
Mobile pre purchase inspections across Sydney and the surrounding NSW regions. We come to the vehicle, wherever it is.
Private seller or dealer, we come to the car. Call with the suburb, make, and model, and we'll handle the rest.
