In September, 580 of the 1,288 EVs sold under $35,000 were demos, almost half. A year earlier it was 50 of 355, about one in seven. They're mostly new Chinese models. Nearly 300 of September's cheap demos were MG4s, and more than 100 were Geely EX2s.

Even when you count only EVs that have had a private owner, cheaper cars have still grown their share, just more gradually. Among second-hand EVs, the under-$35,000 share rose from 27% to 33%. Dealer demos account for the bigger shift, jumping from 50 a year ago to 580 now.

The genuinely second-hand ones are getting cheaper too

Prices for second-hand EVs have fallen too. In September, the same used EV from a brand other than Tesla was worth 9.8% less than a year earlier, a drop of around $3,900 on a typical car. By comparison, used-car prices overall fell 6.5% over the same period, on the same basis.

These figures compare advertised asking prices for cars with the same make, model, age and kilometres, a year apart. They include only cars that have had a previous owner, showing how the value of the same type of car has changed over time, rather than demos pulling the average down. Dealer demos are excluded because they haven't had a previous owner.

Teslas held up better, down 4.0%, or about $1,600 on a typical $39,900 used Tesla.

To put that in perspective, for every $1,000 your EV was worth last September, a Tesla lost about $40 in value over the year, compared with $98 for an EV from another brand.

But the year's decline is relatively small compared with the drop from the original new-car price. A used Tesla Model 3 was selling for about 54% of its original new-car price.

Petrol decides how fast the cheap ones go

Cheaper EVs tend to move faster when petrol prices rise, and March 2026 was a case in point. As unleaded reached around $2.50 a litre, twice as many used EVs sold as in February, with cheaper models moving particularly quickly. The Australian Automotive Dealer Association recorded the same surge, while the number of EVs under $35,000 listed for sale nearly halved in a month.

The share of used EV sales under $35,000 dipped through April and May before climbing back to a quarter in September. The March surge appears to have brought forward purchases from buyers who might otherwise have waited, and it took several months for the cheaper end of the market to regain its share. If petrol prices spike again, March suggests that EVs under $35,000 could be among the first to see demand pick up.

What this means if you're buying or selling now

If you're buying an EV for around $30,000, you could be looking at two very different cars for the same price. A dealer demo might have just 15km on the clock and most of its new-car warranty intact, while a privately sold EV at the same price might have around 65,000km. Before comparing prices, check the build date, kilometres and remaining warranty to understand what you're getting for your money.

If you're selling a Tesla, your car has held its value better than other EVs. If you're selling another EV privately, buyers are likely to see near-new dealer demos listed at a similar price to yours. Their asking price is what buyers compare against yours, regardless of what you originally paid. And with most of their new-car warranty intact, demos can be tough competition.

Peter Willis, Carma's Director of Buying, puts it this way: "At around $30,000, you're looking at two very different EVs. One might be a demo with a couple of hundred kilometres on it and most of its factory warranty intact. The other might be three years old and have done the school run every day. If you're selling the second one privately, check what those demos are listed for, because that's what buyers are comparing your car with."
