What Happens When Your Exact Model Is Not Available
You are not entitled to the identical car, but you are entitled to a replacement of equivalent standard, and that standard is judged by what your car did for you, not by the badge on the boot. If your exact model, trim and colour cannot be sourced, the claim does not collapse. It moves to the next best equivalent.
This guide sets out how equivalence is assessed in New South Wales, the substitution hierarchy used when a prestige model is out of stock, how long it is reasonable to hold out for an exact match, and how to record your reasoning so the claim holds up. It is general information, not legal advice.
Key takeaways
- You are entitled to a replacement of equivalent standard, not the identical car, and equivalence is judged by what your car did for you.
- The substitution hierarchy runs from same model in a different trim through to same tier and body, then adjacent tier, then any roadworthy car.
- A short wait for an exact match can be reasonable, but holding out for months while a good equivalent is available is hard to defend.
- For performance and electric cars, character, charging and real-world use are part of the equivalence argument, not extras.
- Keep a written record of what was offered, when, and why you accepted or declined it, because most disputes are about evidence.

Equivalence is a standard, not a stock number
When someone runs into your car on the Harbour Bridge or in a Chatswood car park, the at-fault driver's insurer is liable for your loss, and your loss includes the use of a comparable vehicle while yours is off the road. The leading Australian authority on this is Arsalan v Rixon, which confirmed that a not-at-fault driver can recover the reasonable cost of a replacement vehicle, and that reasonableness is measured against the vehicle they actually lost, not the cheapest thing that moves.
That is what like-for-like means in practice. It is a standard of equivalence, not a stock number. A 2024 Range Rover Sport D300 is not simply a large SUV. It is a five-seat luxury diesel with 221 kW, 650 Nm, all-wheel drive and a particular presence on the road. A replacement has to do the same job at the same level, which is why the assessment looks at tier, body, drivetrain, seating, performance, transmission and the purpose the car served.
Insurers sometimes argue that any roadworthy car is enough. That argument is weaker when your car is a prestige or performance model and the replacement is a base-spec hatch. The question is not whether the substitute has four wheels and a warranty. It is whether it restores you to a comparable position. Our like-for-like hub sets out the full framework, and how equivalence is assessed for prestige cars walks through the factors assessors actually weigh.
None of this is a guarantee of a particular car. It is a standard to argue from, with evidence.
The substitution hierarchy used when your model is out
When the exact model is not available, the sensible approach is a hierarchy, working down from the closest match. It is not a rigid legal ladder, but it is how a reasonable person, and most assessors, would think about it.
- Same model, different trim or colour. A Range Rover Sport D300 SE Dynamic in a different colour, or a similar model year with a different option pack, is almost always acceptable. The badge, body and capability are intact.
- Same tier and body, nearest specification. A different luxury SUV with similar power, torque, drivetrain and seating. This is where most substitutions land.
- Same tier, different body. A luxury sedan in place of a luxury SUV, or the reverse. Workable for some drivers, a real compromise for others, especially with children, dogs or tools.
- Adjacent tier. A premium mainstream car in place of a prestige one. Usually the point at which you should push back, or at least document why it does not work.
- Any roadworthy car. The insurer's fallback. Rarely equivalent to a prestige vehicle.
Two practical points. First, the hierarchy is about the car's job, not its price. Second, availability in Sydney matters: prestige stock is thinner in January and around school holidays, and delivery to places like Mosman, Paddington or Parramatta takes time to arrange. If you want to see what is actually on fleet and bookable, start with accident replacement cars in Sydney.

Same tier, same body, same job to do
The quickest way to test a substitute is to ask what your car actually did last month. If you have three children in child seats and a boot full of hockey gear, a two-seat coupe is not equivalent no matter how expensive it is. If you tow a boat to Pittwater on weekends, a car without a tow rating is not equivalent. If you drive to Canberra for meetings twice a week, a small hatch with a noisy cabin is a poor substitute for a quiet luxury SUV.
Use this as a checklist when a substitute is offered:
- Tier: luxury, performance or mainstream. It should match.
- Body: SUV, sedan, ute, wagon. It should match, or you should say why it does not need to.
- Seats: if you need seven, a five-seater is a downgrade, not a substitute.
- Drivetrain: all-wheel drive matters on wet roads and gravel driveways.
- Performance: power, torque and acceleration should be in the same conversation.
- Fuel and range: diesel, petrol or electric, and how you refuel or recharge.
- Practicality: tow rating, boot volume, roof racks, child seat anchors.
A luxury seven-seat SUV is a common pinch point. If your own seven-seater is in the shop, a five-seat substitute changes your daily logistics. Our guide to seven-seat prestige SUV replacement equivalence goes deeper, and a Genesis GV80 with seven seats is often the natural like-for-like answer.

Not at fault? Start your claim
A like-for-like replacement car while yours is repaired. No cost to you when the other driver is at fault.
Start my claimHow long is it reasonable to wait for an exact match
There is no fixed number of days in the legislation, and anyone who tells you there is is guessing. Reasonableness is judged on the circumstances: how long your repair is expected to take, how rare your car is, what alternatives exist, and whether waiting leaves you without transport.
In practice, a short wait is usually fine. A week or two to source a close match is defensible, particularly for a low-volume performance model. What is harder to defend is holding out for months while a perfectly good equivalent sits available, especially if you are relying on a hire that someone else is paying for. Insurers and courts tend to look at whether you mitigated your loss.
A workable rule of thumb:
- If your repair is booked and expected to take three weeks, a substitute that matches tier, body and seats is reasonable now.
- If your exact model is genuinely due back on fleet within a few days, waiting is reasonable.
- If the only exact match is months away, take the closest equivalent and document why it is close enough.
Timelines also depend on parts. A prestige repair in Sydney can sit in a workshop in Alexandria or Silverwater waiting on a bumper or a sensor from overseas, and that delay is not your fault. Our page on how long prestige car repairs take in Sydney explains the common bottlenecks, and insurer delays on a replacement car covers what to do when the other side stalls.
The point is to keep moving. A substitute you can use today usually beats an exact match you cannot.
Performance cars and the character problem
Performance cars are the hardest substitution, because so much of what you paid for is character: steering feel, exhaust note, throttle response, the way a car sits on the road. A BMW M car or an AMG is not just faster than a standard sedan. It is a different experience, and owners notice immediately.
Insurers often treat performance as a luxury rather than a need. That is where the argument has to be specific. If your car is a daily driver, the substitute needs to be usable every day. If it is a weekend car, the substitute still needs to be comparable when you use it. Either way, the test is equivalence, not identical specification.
A few practical points for performance owners:
- Match the tier and the character as closely as you can. A performance SUV is a better substitute for a performance SUV than a base model of the same brand.
- Be realistic about track use. A hire car is not a track car, and no assessment will treat track days as a need.
- Document what you actually use the car for: commuting on the M2, weekend runs on the Old Pacific Highway, towing, family duty.
- If the substitute is a genuine step down, say so in writing and explain the practical effect.
Our performance car replacement equivalence guide and the BMW M and AMG replacement cars page cover the detail, and performance car replacement in Sydney lists what tends to be available.
If your performance car is off the road, the substitute still has to do the job your car did. Character is part of that job, and it is worth arguing for.
Electric cars and charging as part of equivalence
If your car is electric, equivalence includes charging. A substitute that cannot use your home wallbox, or that cannot do your regular run without a long detour, is not equivalent in any practical sense. This is a newer argument, and it is a strong one when it is specific.
What to think about:
- Range and real-world use. If your commute is Castle Hill to the CBD and back, a short-range substitute changes your week.
- Charging speed. If you rely on fast charging, a car that charges slowly is a downgrade.
- Home charging. Most home wallboxes are not universal. Check the plug and the app before you accept.
- Charging costs. Keep receipts for public charging. They are part of your loss.
- Family and load. A seven-seat electric SUV with 568 kW and 967 Nm is a very different proposition from a small electric hatch.
Where an electric prestige SUV is the right substitute, a Tesla Model X P100D can be a close fit for a seven-seat electric brief, and it can be self-drive or chauffeured.

Our electric prestige replacement car equivalence page sets out the full argument, and replacement by car type covers how body style and powertrain shape the assessment.
Charging is not a nice-to-have. It is part of what your car did, and it belongs in the comparison.
Recording the reasoning so the claim holds up
Most disputes about substitutes are not about the law. They are about evidence. If you can show why a particular car was a reasonable equivalent, and why the alternative offered was not, you are in a much stronger position.
Keep a simple file:
- Your car's details: make, model, trim, year, body, seats, drivetrain, fuel, and the features you rely on.
- How you use it: commute, school run, towing, business travel, with rough weekly distances.
- What was offered and when: dates, times, who said what, and by which channel.
- Why a substitute was accepted or declined: one or two sentences is enough, but write them at the time.
- Photos and documents: the damage, the repairer's estimate, the police report if there was one, and any correspondence.
Keep it factual. "The offered vehicle has five seats and no tow rating; I have three children and tow a trailer" is persuasive. "The offered vehicle is rubbish" is not.

Good records do not guarantee an outcome. They do make the reasonable answer much easier to see.
What you can do if the substitute genuinely does not work
Sometimes the substitute is simply wrong for your life. It is too small, too slow, cannot tow, cannot fit the child seats, or cannot make your regular trip without a charging detour. When that happens, do not just accept it and complain later. Act.
- Say no in writing, with reasons. One or two specific sentences about the practical problem.
- Ask for the next option. Give the other side a chance to fix it before you escalate.
- Check what else is available. Availability changes daily, and a car that was not there on Monday may be there on Thursday.
- Keep your own costs down. If you must hire something yourself in the meantime, keep it reasonable and keep every receipt.
- Get advice early. If the insurer is refusing to engage, a solicitor who does this work can tell you where you stand. This article is general information, not legal advice, so talk to your solicitor about your circumstances.
If you are paying for the hire yourself while the claim is sorted, our how credit hire works page explains the usual arrangement, and cost and payment covers what to expect. To see what can be arranged now, check availability at not-at-fault accident replacement.
The goal is to get you back into something comparable quickly, without weakening your position. If a substitute does not work, say so clearly and move to the next best option.
The short version for prestige owners
If your exact model is not available, the claim does not fail. It shifts to the closest equivalent, judged by tier, body, seats, drivetrain, performance and the job the car did. Insurers will sometimes test whether you will accept less. You do not have to accept a car that does not do what yours did, but you do have to be reasonable about how long you wait and what you turn down.
The practical sequence:
- Confirm the other driver was at fault and get the details.
- Tell your insurer and the at-fault insurer what your car is and what it does.
- Ask for a like-for-like replacement, and explain what like-for-like means for your car.
- If the exact model is out, work down the hierarchy and document why each option was accepted or declined.
- Keep receipts, messages and a short written record of the reasoning.
Our first 24 hours guide covers the immediate steps, not-at-fault explained sets out the basics, and replacement by area and business and fleet cover local and fleet situations. If you are a repairer, solicitor or broker, partners and referrals explains how referrals work.
Start with the car you lost, not the car that happens to be free. That is the standard, and it is worth holding to.
