Petrol, diesel, hybrid, plug-in, electric — seven fuel types, every new vehicle in Australia, and not a single place that estimates what any of them may cost to own over time. Until now.
Carreb is Australia's first AI-powered platform that combines estimated running costs and tailpipe emissions into one clear score: the CORE™ Rating. So you stop guessing — and start choosing with confidence.
Cut the noise. Keep the money. That's Carreb.
Where do Australians turn when buying a car? Dealerships, sales and review sites, annual cost reports, AI tools — all with the same blind spot: none of them estimate what the car may cost you to own over time.
Dealerships are set up to sell — not to estimate your long-term running costs, show you ownership value across fuel types, or check whether that shiny new EV's real-world range suits your lifestyle. Range anxiety is real. Getting the full cost picture from a showroom visit? That's not what they're built for.
Built to sell you a car or tell you how it drives — not to estimate what it may cost you to own. Running costs, emissions, your finances — not their problem. And resale estimates? Built for a two-drivetrain world (petrol and diesel) — and they can't give you one until thousands have already been sold. In a market with seven fuel types and new models landing monthly, that's too late. Carreb gives you an estimated resale value before you buy. It's one part of the CORE™ Rating — a score combining estimated Cost of Ownership, CO₂ impact, and potential savings. Built on current data, not yesterday's assumptions.
Annual cost-of-ownership reports from motoring clubs cover a handful of models — but they're often outdated within months and limited to popular vehicles. Generic AI tools? We tested ChatGPT, Gemini, Grok, DeepSeek, Claude and Copilot. Different answers every time, same day, same car. No consistent methodology. Not calibrated for Australia. Whether it's a static PDF or a confident-sounding chatbot, neither personalises to your situation across 3,000+ vehicles and seven fuel types. Life's too expensive for that.
"I founded Carreb because buying a car has become unnecessarily complex at the worst possible time — when families are already making real sacrifices, and the wrong decision can take even more from the life they're trying to build. I believed there had to be a better way — so I built it. For every Australian who deserves clarity over confusion."
— Jock Marmotta, CEO & Founder
We believe every Australian deserves transparent, intelligent information when choosing a vehicle. No agendas. No jargon. Just the insights that matter to your wallet and the planet.
Save Smarter. Drive Greener. Live Better.
Carreb was born from a simple belief: you shouldn't need a degree in economics or engineering to make one of the biggest financial decisions of your life. For many Australians, a car is not a luxury — it is essential. It deserves clarity.
We don't push brands. We don't profit from dealers. We give you the estimated cost and emissions data to help you decide which car may fit your life — based on what you care about most: potential savings, sustainability, and simplicity.
Carreb is completely independent. We don't sell cars. We don't take commissions from dealers or manufacturers. We don't profit from your choices. Our revenue comes from you — through a free starter plan, a one-time Car Buying Sprint, or optional annual plans. That's it. No hidden incentives, no sponsored rankings, no manufacturer bias.
Every analysis is powered by Australian data sources: fuel prices, registration costs, insurance rates, maintenance expenses, and government tailpipe emissions databases. We're transparent about our sources, our methodology, and how we make money — because you deserve to trust the tools that inform one of your biggest financial decisions.
For most Australian families, a car is the second-biggest purchase they'll ever make — and the running costs don't stop at the sticker price. Fuel, insurance, registration, servicing, tyres, depreciation — it adds up to thousands every year. Carreb's CORE™ Rating estimates all of it, across 5 years, so you can see which cars give you more life for your money.
Seven fuel types. Hundreds of models. New releases every month. No one can keep up — and no one should have to. Carreb does the work for you: it ranks vehicles by estimated total cost of ownership — including estimated resale value — and tailpipe emissions, tailored to what matters most to you. One score. One clearer picture.
Manufacturers spend millions making cars sound green. Carreb uses official Australian Government tailpipe emissions data — not marketing brochures — to show you what actually comes out of the tailpipe. Because "eco-friendly" should mean something measurable, not just a badge on the bonnet.
Not global averages. Not US estimates. We source from official Australian Government databases — including Green Vehicle Guide tailpipe emissions, FCAI vehicle specifications, and real-world fuel, insurance, registration, and servicing costs. Every data point is verifiable and auditable.
Unlike static annual reports or generic AI tools that give inconsistent answers, Carreb uses a structured calculation method purpose-built for Australian vehicle costs. It estimates 5-year cost of ownership across every cost category, balances estimated costs and emissions to your chosen priorities, and produces consistent, repeatable results — not dated PDFs or different answers every time you ask.
All of this work comes together in one clear score: the CORE™ Rating — combining estimated Cost of Ownership with tailpipe CO₂ emissions. It's designed to help you understand both the estimated financial and environmental impact of a vehicle — in a single number.
Every CORE™ Rating shows you the data inputs and assumptions behind the estimate — fuel costs, insurance, registration, servicing, depreciation, and more. You can see what goes in, update key variables to better reflect your circumstances, and refine the estimate so it works harder for your decision. The smarter your inputs, the sharper your CORE™ Rating.

"The right information shouldn't be a privilege."
I founded Carreb because buying a car has become unnecessarily complex at the worst possible time — when many families are already making real sacrifices, and the wrong decision can take even more from the life they're trying to build.
For many Australians, a car is not a luxury. It is essential. But with hundreds of models, multiple fuel types, conflicting opinions, and hidden ownership costs, choosing the right one has become harder than it should be.
I believed there had to be a better way — so I built Carreb to bring clarity, independence, and common sense to one of life's biggest financial decisions.
I spent my career solving complex problems by stripping them down to what actually matters. Cars needed the same treatment. My mission is simple: make car buying clearer, fairer, and more aligned with the future people actually want.

I joined Carreb because its mission resonates deeply. Clarity and simplicity in one of life's most confusing decisions—that's exactly what technology should do. Helping Australians understand what a car will actually cost them? That matters. And I'm here to make sure the platform behind it is rock solid, secure, and genuinely useful.
