Certified pre-owned car vs dealer demonstrator: key differences when buying a used car

Should I buy a dealer demonstrator car in Australia?

Dealer demonstrators are vehicles that customers can test drive before committing to a new car in that specification. Demos typically rack up a few thousand kilometres over a period of 12 months or less. Then they are retired to the used-car lot.

Buying a demonstrator can save thousands by eliminating many of the on-road costs involved when purchasing a new vehicle, such as dealer delivery. Dealers can also make money on demonstrators because the on-road costs they absorb may be claimed as a tax offset, as they are costs incurred in doing business.

Not every demonstrator is showroom-floor-only stock. A car badged as a 'demo' may have had an earlier role as an executive car or courtesy car before reaching the dealership and being sold as a demonstrator or ex-demonstrator, which can come as a surprise to buyers expecting a near-new car that's barely been driven.

A used demonstrator may be on sale because it has been superseded by a newer model with a facelift, enhanced comfort and convenience features, better performance or improved safety.

On the other hand, the car might be extremely close to brand-new, with very few kilometres on the odometer. In this situation, the dealer may have 'pre-registered' the car to sell as a demonstrator and boost their new-car sales results (which are recorded in Australia when the car is registered). This can be advantageous for buyers, who may be able to take home an essentially new “used car” with the on-road costs covered and most of the factory warranty term still in place.

A word of caution concerning demonstrators for high-performance models: the demo may have been subjected to varying degrees of mechanical abuse from over-enthusiastic drivers. RACV recommends that, at the very least, a buyer contemplating the purchase of a high-performance demonstrator should arrange an independent vehicle inspection.

In general, however, modern cars can usually withstand harder driving during the first year, and the factory warranty continues to cover the buyer of a demonstrator for the remaining warranty period.

Pros of buying a dealer demonstrator car in Australia

• Typically up-to-date specifications and features.
• Lower purchase price than a new car.
• Covered by factory warranty for years to come.
• First service will have been carried out by the dealer.
• Depreciation won’t be as bad in successive years.

Cons of buying a dealer demonstrator car in Australia

• May have been the subject of abuse from test drivers.
• May have been a used car before it became a demonstrator.
• Potential to become outdated in a shorter space of time.
• Resale value will suffer slightly if the demo was built a year earlier.

Should I buy a certified pre-owned car in Australia?

Car buyers may be unfamiliar or confused by the term 'certified pre-owned'. In simple terms, a certified pre-owned car is a used vehicle that has been assessed by an authorised dealer or manufacturer-backed program before being offered for sale.

For some buyers, certified pre-owned can offer a useful middle ground between a standard used car and a near-new demonstrator. These vehicles are typically recent models sold through authorised dealers, with the reassurance that they have met certain inspection, age, kilometre and condition requirements.

A certified pre-owned car may also come with a manufacturer-backed or dealer-backed warranty that extends beyond the statutory warranty. In Victoria, a statutory warranty generally applies to eligible used cars bought from a licensed motor car trader if the vehicle is less than 10 years old and has travelled fewer than 160,000km. It lasts for three months or 5000km after purchase, whichever occurs first.

Certified used cars are often more affordable than demonstrator models, but they usually cost more than comparable uncertified used cars. That higher price reflects the added checks, dealer backing and any extra warranty or roadside assistance included in the program.

The exact criteria vary by brand and dealer, but a certified pre-owned car will usually need to be a relatively recent model, in good condition and within a set odometer limit. It should also have passed a detailed mechanical inspection covering key components (around 100) that are prone to wear, damage or premature failure.

A certified pre-owned vehicle should also come with a documented service history, and it may still be covered by the remaining balance of the original factory warranty. Buyers should ask exactly what has been inspected, what warranty applies, and whether any exclusions or servicing conditions are attached.

Because certified used cars can carry a premium, it is still worth comparing prices against similar uncertified vehicles and negotiating where possible. A lower odometer reading, stronger warranty or more complete service history may justify the extra cost, but buyers should not assume every certified car represents better value.

Dealers that sell certified pre-owned cars usually also sell new cars from the same brand. A buyer who is happy with their certified used car may be more likely to return to the same dealer in the future, giving the dealer and car company another way to build long-term customer loyalty.

How to choose between a dealer demonstrator car and a certified pre-owned vehicle

^{* Circumstances will vary}

Certified pre-owned versus dealer demo: key points for buyers

The decision to choose a dealer demonstrator car over a certified pre-owned car – or vice versa – will probably boil down to the specific car and the price being asked.

Before committing, factor in the full cost of ownership, including repayments, insurance, registration, stamp duty, servicing and likely depreciation. RACV Car Loans can help eligible buyers finance a new, demo or used car, with used car loan options available for those buying a certified pre-owned vehicle.

Both a dealer demonstrator car and certified pre-owned car offer significant savings over the cost of a brand new car. You miss out on the chance to choose your own body colour and make other detail changes to the specification, but there is no waiting time for delivery from the factory and the car in question is likely to have most, if not all, the modern driving dynamics, safety features, low running costs and creature comforts that come with a new vehicle.

There's the likelihood that a demo sold today will soon be overtaken by a 'freshened' model with a longer standard equipment list. Similarly, a certified pre-owned car is likely to have been superseded. This, however, should be reflected in the purchase price and, in both cases, buyers can usually be confident the car in question should provide years of sterling service into the future.

Having the balance of the new vehicle warranty also helps provide peace of mind.

Compared to a certified pre-owned car, the demonstrator will remain 'new' for longer and it may have some important features the certified used car lacks.

On the flipside, lower depreciation of a certified pre-owned car may be more important to a buyer intending to replace the car in few years' time.
