Automotive marketing works when the price, the car and the business all check out before anyone picks up the phone. Buyers research for longer now: in carsales' 2026 research, 63% backtracked at least once on the way to a decision. So dealers win with honest drive-away prices and complete listings, and workshops win by being easy to find and clear that owners can choose an independent repairer. In NSW, even the wording of a car price is regulated.
Written by Dan Picken, founder. Last checked 6 November 2026.Sales are FCAI VFACTS figures reported by CarExpert. The warranty figure is from a 2026 survey for the Australian Automotive Aftermarket Association, reported by CHOICE, and the reports figure is from the ACCC December 2025 report on second-hand cars. Add almost 3,200 new car dealers and thousands of independent workshops, and you get a crowded market with a trust problem, and a widely held myth that independent mechanics can correct with plain facts.

How people buy a car
A buyer compares models and listings on comparison sites and brand sites, asks Google or an AI tool, checks out the dealer, and often backs out and starts again before booking a test drive. Choosing a mechanic is shorter: a search, the map, a few reviews and a phone call.
The psychology
A car is one of the biggest purchases most households make, and buyers find it hard to know who to believe: more than 62% struggle to know what information to trust early on. These are the questions behind the enquiry.
01
The first number sticks. If it grows by the time the contract is printed, the buyer feels tricked, and in NSW the ad may be in breach: dealer ads can't use 'on-road costs' wording for statutory charges.
Show them: A drive-away price, or the dealer charges in dollars and a clear total.
02
59% of buyers worry about making the wrong decision, and many stop and start again. The fear of a bad car outweighs the pull of a good deal.
Show them: Straight comparisons, the warranty in plain words, and what happens if something goes wrong in the first weeks.
03
A used car buyer can't see inside the engine. Facts they can check do the persuading, not adjectives like 'immaculate'.
Show them: Service history, the rego or stock number, a correct odometer reading, and photos of the wear as well as the shine.
04
Weekly repayment ads are everywhere in used cars, and the ACCC has heard of cases where actual repayments were higher than the advertised ones.
Show them: The full price next to any weekly figure, plus the term, and the comparison rate when a rate is shown.
05
Plenty of owners think so, but the ACCC says consumers can choose an independent repairer. For workshops, that myth is the biggest barrier and the biggest opening.
Show them: For workshops: one line saying servicing to the manufacturer's schedule keeps a new car's warranty.
From my audits
These patterns come up again and again in dealer and workshop marketing, and they're the first things I'd check.
An ad or listing price that isn't the drive-away price, with the extra costs only appearing in small print or on the contract.
Listings and ads for cars that sold days ago, which waste clicks and make buyers doubt the rest of the stock.
Sales, service and parts squeezed into one profile, with sales hours showing when someone is trying to book a service.
Website, comparison site and Facebook leads landing in different inboxes, with no record of which ones became sales.
Mechanics who never say plainly that log book servicing to the manufacturer's schedule keeps a new car's warranty.
Drive-away price checker
Enter the car's numbers and the price line from your ad or listing. It works out the total, writes a line that fits the NSW dealer rules, and flags wording that doesn't. Checked against NSW Fair Trading and ACCC guidance on 6 November 2026. The starting numbers are made up.

Verdict
A marketer's check of the wording, not legal advice. Outside NSW, check your state's dealer rules too.
AI search
In a carsales survey of more than 2,000 Australians, 35% said they use or plan to use AI in their car search, and more than 70% of them chose ChatGPT. Google says its AI features run a set of related searches behind one question and link to the pages that support the answer.
AI tools piece an answer together from your site, your Google profile, comparison sites and reviews. If your hours, makes and services differ between them, expect a muddled answer.
'Will an independent service void my warranty?' is the kind of thing AI answers in a sentence. Workshops that publish the plain answer, with its conditions, give it something accurate to use.
What to do now
My take: AI tools favour the business that's easiest to describe accurately. Car businesses that publish plain, current facts leave it the least room to guess.
Australian rules
Car advertising has more specific rules than most industries, and NSW adds its own. These come up most in marketing, checked on 6 November 2026, NSW first.
NSW dealer ads must show dealer charges in dollars, say government charges apply if they're not included, and not use 'on-road costs' wording for statutory charges. A priced used car needs its rego or stock number.
If you show part of a price, the Australian Consumer Law needs the total as a single figure, just as prominent. When that rule began in 2009, the ACCC said a car price 'plus on-road costs' was no longer enough.
Since 1 September 2025, NSW dealers selling online must show their licence number on their website and advertising and use a .au web address. Dealers already online had until 1 December 2025.
Consumer guarantees apply to cars from a licensed dealer, and a voluntary warranty can't replace, change or take them away. NSW used cars under 10 years and 160,000 km carry a 3 month or 5,000 km dealer guarantee.
The FCAI's voluntary code, administered by Ad Standards, says ads shouldn't show unsafe driving, speeding or other road law breaches, and its explanatory note says to avoid drawing attention to speed or acceleration.
Under the Motor Vehicle Information Scheme, repairers can buy service and repair information at no more than a fair market price. In August 2026 the ACCC took Subaru to court, its first case under the scheme.
A marketer's summary, not legal advice. Finance ads and the other states are covered on the car advertising rules page.
The channel mix
The automotive hub
Not always, but the price can't mislead. NSW dealer ads must show dealer charges in dollars and say government charges apply when they aren't included, and can't use 'on-road costs' wording for statutory charges. A drive-away price is the simplest way to comply.
Not as a way around the total. The ACCC said in 2009 that a car price 'plus on-road costs' is no longer enough, and NSW dealer ads can't use 'on-road costs' wording for statutory charges.
Not if the servicing follows the manufacturer's requirements. The ACCC says consumers can choose an independent repairer, yet a 2026 survey found 44% believe they must go back to the dealer.
Usually. Cars under 10 years old with less than 160,000 km come with a dealer guarantee of 3 months or 5,000 km, whichever comes first, on top of the consumer guarantees.
Yes. Since 1 September 2025, NSW dealers selling online must display their licence number on their website and advertising material.
That's the aim of the Motor Vehicle Information Scheme: Australian repairers can buy service and repair information for passenger and light goods vehicles made from 2002, at no more than a fair market price.
