Buy now or wait for Q4? The 2026 used-EV timing call that could save — or cost — you £2,000

For the first time in three and a half years, a used electric car you look at this month won’t be cheaper next month than it was last month. Motor Trader reported on 8 June 2026 that used EV values were static in May, the first month without a year-on-year fall since December 2022, ending 40 consecutive months of decline. If you have been sitting on your hands waiting for prices to bottom out, that is your signal: the bottom may already be behind you.

So the question I keep getting asked, buy now or hold for the usual Q4 dip and pocket a couple of grand, has changed shape entirely. It is no longer “how much cheaper will it get.” It is “am I about to pay more for waiting.” Here is how I’d read it, and where that £2,000 actually hides.

Forty months of falling prices just stopped (used-EV)

Let me be precise about what stabilisation does and doesn’t mean. It does not mean prices are climbing across the board. It means the steady bleed that has defined the used EV market since the back end of 2022, the thing that made every buyer feel like a mug for not waiting one more month, has, for now, run out of road. May was flat. Not up much, not down. Flat.

That matters because the entire “wait and save” strategy was built on momentum. For 40 months, doing nothing was the smart play; the car you wanted got cheaper while you slept. Strip the momentum out and the maths inverts. Now, waiting costs you the interest on the cash you’re sitting on, the depreciation on whatever you’re driving in the meantime, and the risk that the very car you’ve been tracking gets sold to someone less hesitant.

The demand surge that’s eating the discount

The reason prices stopped falling isn’t sentiment, it’s volume. The SMMT recorded 86,943 used battery-electric cars changing hands in Q1 2026, up 32% year on year and 4.3% of the entire used market. That is a record, and it is the kind of demand that puts a floor under prices far more reliably than any forecast.

You can feel it in how fast the metal moves. Auto Trader’s April index had used EVs selling in 24 days against 27 for petrol, and the sweet-spot three-to-five-year-old cars going in 25. When stock turns that quickly, dealers have no reason to discount, and the bargain you spotted on a Friday is genuinely gone by the following weekend. This is the opposite of a buyer’s market sitting on its hands.

For 40 months, doing nothing was the smart play. Strip the momentum out and the maths inverts, now waiting is the gamble, not buying.

Where the £2,000 actually lives

Here’s where I’ll push back on the headline a little, because the timing call isn’t the same for every car, and the £2,000 swing only really exists at one end of the market.

At the affordable end, the seasonal game barely registers. A 2019–2021 Nissan Leaf now averages £8,308, per AA Cars, and yes, that is still down 24.6% year on year, the lingering tail of the long decline. But on a car that cheap, a typical Q4 softening of a few per cent is a few hundred quid, not two thousand. Against that you’re risking the recovery: if Leaf values follow the wider market and flatten or tick up, you’ve waited six months to save the price of a service. I wouldn’t.

The £2,000 lives at the top of the used-EV stack. A 2020–2022 Tesla Model 3 spans roughly £18,000 to £26,000. On a £26,000 car, the historical Q4 seasonal dip, the slow autumn-into-winter softening that AA Cars’ trend data has shown year after year, is where a genuine four-figure saving could come from. That is the one car where I think holding into Q4 is a defensible bet rather than wishful thinking. The Renault Zoe, at £9,000–£13,000, sits in between: enough value for seasonality to matter a little, not enough for it to be decisive.

The older-EV trap nobody’s pricing in

If you’ve convinced yourself that “EVs always depreciate,” one number should stop you cold. EV Fleet World reports that values of 10-to-15-year-old EVs rose 8.4% year on year, outperforming the wider used market outright.

That is not a rounding error; it’s a structural signal. The oldest, cheapest electric cars, the early Leafs and i3s, have become genuinely scarce and genuinely wanted, by people who want electric motoring without a finance agreement. If you are shopping the bottom of the market specifically to wait it out, you are waiting for a price that is already moving the wrong way for you. The “wait for Q4” thesis quietly collapses here: there is no seasonal dip coming for a car class that is appreciating.

What I’d actually do before September

So, a clear call, because fence-sitting helps no one. If you’re buying a Leaf, a Zoe, or anything under roughly £12,000, buy now. The stabilisation is real, demand is record-high, the cars sell in under a month, and the most affordable end is the one category that’s actively firming up. Waiting for Q4 to shave a few hundred pounds off a car that might not be there, or might cost more, is a bad trade.

If, and only if, you’re chasing a higher-value Model 3 in the low-to-mid £20,000s, there’s a real argument for holding into Q4 and letting the seasonal softness do its work, that’s where the £2,000 genuinely could materialise. But go in clear-eyed: you are betting that an autumn dip outweighs a market that just ended 40 months of falling prices and is turning stock in 24 days. That is no longer the safe bet it was last year.

What would change my mind on all of it? A fresh wave of cheap new-EV deals or a finance-rate cut that floods the used market with part-exchanges, that’s the one thing that could reopen the discount window. Short of it, the era of waiting being the clever move is over. For most buyers, the smart play in 2026 is to stop watching the price and start driving the car.
