You Bought a Chinese Car. Now the Finance Industry Has No Idea What It's Worth.

The Boom Is Real. The Resale Risk Is Also Real.

Let's start with the numbers, because they're genuinely extraordinary. BYD's Australian sales are up 124% year-on-year in the first half of 2026, hitting 52,335 units. Chery is up 77% to nearly 25,000 sales. Four Chinese brands now sit inside the VFACTS top 10. In June 2026, BYD came within 243 units of overtaking Toyota as Australia's best-selling brand for the month — something that would have sounded like science fiction two years ago.

The reason is simple: these cars are genuinely good value. More features, longer warranties, competitive finance, all below $50,000. Australians facing record fuel prices and a cost-of-living squeeze are doing the rational thing.

But here's what the salesperson doesn't put on the whiteboard when you're talking monthly payments: how fast will this car lose value, and what does that do to your loan?

Depreciation Is the Hidden Engine of Your Car Finance Deal

Every car finance product — whether it's a standard loan, a balloon payment loan, or a Guaranteed Future Value (GFV) loan — is built on an assumption about what your car will be worth at the end of the term. Lenders call this the residual value. If the lender gets it wrong, you wear the consequences.

Here's the core problem with Chinese brands right now: the resale market for most of them is still immature. There simply isn't enough Australian data yet for lenders — or anyone — to confidently predict where a 2026 BYD Atto 3 or Chery Tiggo 7 will trade at in 2029. And early signals are not encouraging.

Research tracking RedBook data found that the BYD Atto 3's 2024 model had already depreciated by 35.84%, while the Chery Tiggo 7 Pro dropped by a staggering 42% in value in just over a year. For comparison, a 2024 Toyota RAV4 Edge had lost just 4.3% of its value over the same period. That's not a small gap — that's a financial canyon.

What This Means If You're Financing a Chinese Car Right Now

If you take out a standard car loan over five years on a $45,000 Chinese SUV, and that car depreciates 40% instead of the 20% the lender modelled, you could find yourself deeply underwater — owing more on the loan than the car is worth. That's called negative equity, and it's one of the most common ways Australians get trapped in bad car finance situations.

It gets worse if you have a balloon payment at the end of your loan. The balloon amount is set at the start based on an estimated future value. If the car is worth less than that balloon when the term ends, you either have to pay the difference in cash, refinance (often at a worse rate), or hand back the car and still potentially owe money. None of those options feel good.

The same logic applies to GFV (Guaranteed Future Value) loans — a product where the lender sets a guaranteed buyback price at the start. On paper, a GFV loan is meant to protect you from depreciation risk. The lender absorbs the downside if the car is worth less than the GFV at term end. But there's a catch: most GFV contracts are loaded with conditions — kilometre limits, wear-and-tear clauses, and return fees — that can wipe out that protection entirely.

The BYD Build-Year Scandal: A Cautionary Tale

This week, a story broke that illustrates just how much the depreciation question matters in practice. BYD Australia was found to have sold a number of 2025-built vehicles to customers who believed they were buying 2026 models. The company attributed it to an administrative error in how factory exit dates were recorded. BYD initially offered affected owners just $1,100 in compensation — before being forced into a full reversal offering refunds or replacement vehicles after public outcry.

Why does a build year matter so much? Because in the automotive market, a car's build year is its financial heartbeat — especially for EVs, which already face steep depreciation curves. A car showing a 2025 build year on its papers immediately loses ground on its trade-in and resale value compared to a 2026-plated equivalent. The CEO of the Consumer Policy Research Centre said the depreciation ramifications could leave owners "seriously out of pocket."

This isn't an indictment of BYD as a brand. The incident highlights something broader: when depreciation is already uncertain, any additional variable that affects perceived value — build year, model updates, price cuts by the manufacturer — hits Chinese car owners harder than it hits Toyota or Mazda owners. That's the market reality in 2026.

The Lender Is Guessing Too — And You're Taking the Risk

Here's something the finance industry doesn't say out loud: when a lender sets a residual value on a Chinese car in 2026, they're making an educated guess based on limited local data. The resale market for many of these brands is, as one industry guide put it, "still maturing."

The RBA reports that the average fixed-rate personal loan (including car loans) sits at 9.06% p.a. — well above the lowest advertised rates. Add an uncertain residual value into that equation, and the true cost of financing a fast-depreciating vehicle becomes very hard to calculate at signing. Most Australians never try.

Meanwhile, lenders are making their own calculations. The automotive finance market in Australia is growing fast — projected to reach USD $7.59 billion in 2026 — and Guaranteed Future Value programs are a key part of that growth. Lenders use detailed resale data to set GFV prices. For established brands with decades of Australian resale history, that data is solid. For a brand that's been in Australia for two years and is releasing new model lines every six months, that data barely exists.

What You Should Actually Do Before You Sign

• Search the current resale value of your exact model on RedBook or CarsGuide before you agree to any finance terms. What is a 2023 or 2024 version of this car selling for today? That's your early depreciation signal.
• Ask the lender what residual value they've used to calculate your balloon or GFV amount. Get it in writing. Compare it to current used-car listings for similar models.
• Check the fine print on any GFV or balloon contract for kilometre caps, condition requirements, and what happens if you go over. These clauses are where the protection disappears.
• Consider the term length carefully. A five-year loan on a fast-depreciating car is riskier than a three-year loan, because the value gap between what you owe and what the car is worth has more time to grow.
• If you're buying for business use, note that the ATO car depreciation limit for the 2026–27 financial year is $69,883 — meaning the maximum value you can depreciate is capped, regardless of what you paid. Speak to a financial adviser or registered tax agent about how this applies to your situation.
• Don't let the weekly payment be the only number you focus on. A low weekly repayment can still leave you with a large residual bill or a car worth far less than your remaining loan balance.

The Alternative: Finance That Builds In the Depreciation Risk Honestly

This is exactly why Milam was built the way it was. On a standard car loan or a GFV product, the depreciation risk sits largely with you — either through negative equity, a balloon payment shortfall, or conditions that void your protection. Milam flips the model: lower weekly payments, and an equity payout when you return the vehicle. Instead of walking away from a finance term with nothing but a car that's lost 35–42% of its value, you get money back.

That's not a magic trick. It's just a structure that's honest about depreciation from day one — and rewards you instead of punishing you for it.

If you're one of the many Australians considering a Chinese car purchase in the second half of 2026, the brand choice might be smart. The finance structure you use matters just as much as the car you choose. Make sure you understand both before you sign anything. And always speak to a financial adviser before making major finance decisions.
