Biggest new car price drops

These are the five new cars with the highest month-on-month price decreases, according to our unique pricing data.

Peugeot’s recent price cuts for much of its electric range (and some significant dealer discounts) explain why two of the brand’s electric models appear in the table. In fact, Peugeot had a clean sweep of the top five. For variety we’ve included only two of them in the table above, but the other models were the Peugeot e-2008 (-16.3%, down £4,650), Peugeot 2008 (-13.6%, down £3,426) and Peugeot e-5008 (-12.3%, down £5,400).

While the Citroen e-C3 is available with discounts from some dealers, the brand has recently altered the model’s trim level structure. This means that certain examples of the now-discontinued ‘Standard Range Plus’ model are now being discounted by dealers to make space for the newly introduced ‘Collection’ model.

Toyota recently introduced a 0% finance deal with a £3,500 deposit contribution on its bZ4X model (when financed with PCP), which explains its slight month-on-month price decrease.

Finally, the Explorer is also available with a 0% APR PCP finance deal and a larger discount of £7,500, while some dealers are advertising heavily-discounted Explorer cars for sale too.

Biggest new car price increases

These are the five new cars with the biggest month-on-month price increases.

Compared to price decreases, few cars have seen large price rises over the last month.

Even though the Mokka is currently available with a 0% finance deal and a small deposit contribution from Vauxhall, the contribution is quite small and fewer dealer discounts are now available compared to last month.

This is also true of the Dacia, which is now only available with a £500 finance deposit contribution, relatively small dealer discounts and a high 6.9% APR rate when financed through PCP.

Like the similar e-C3, the C3 Hybrid is available with discounts from some dealers. The earlier ‘Plus’ model of the hybrid C3 has also been discontinued, and as Citroen isn’t under pressure to sell them (unlike the e-C3, because of the zero-emissions vehicle mandate), the brand and dealers can reduce the discounts they offer on the C3 Hybrid.

Audi’s Q7 range is being replaced this year, and this includes the SQ7. As this generation of Q7 is no longer built by Audi, there’s no hurry for dealers to offer discounts to shift stock as the new Q7 isn’t in the UK yet.

Now BYD has introduced a plug-in hybrid version of the Atto 2, it appears that the brand is offering less of a discount on the electric Atto now.

Bestselling cars: average cash discounts

Our data shows that for the UK’s best-selling cars in June 2026, their cash prices haven’t changed much compared to last month.

As Tesla sells its cars through the ‘agency’ model and doesn’t offer discounts, it’s not surprising to see its prices are unchanged.

Discounts on the Kia Sportage continue, with its price falling by £206 having fallen by around £500 last month.

Before buying a new car: what you need to prepare

It helps if you’re clear beforehand on exactly which model, engine/motor and trim level you’re interested in. Manufacturer websites are a good place to check if you’re buying new, but you can also get an idea from our new and used car reviews.

When buying new, look for manufacturer discounts online and in ads, and be prepared to bargain – dealers might still have their own margin to play with on top of what’s offered by the manufacturer.

Some dealers also regularly advertise heavily discounted new cars on sites such as Carwow and Autotrader. Even if the cheapest car you're interested in is hundreds of miles from where you live, it can be useful to see other dealers' list prices for the car you're after. Take any quotes with you to show the salesperson.

Most new car buyers need some form of finance, and dealers are keen to offer their own finance packages. However, they may not be the most suitable or cheapest way to buy a new car. Our expert guide to car finance explains the pros and cons of the most popular methods.

Whether or not you want to take out dealer finance, it can pay to express an interest in it. Some dealers are prepared to offer a bigger discount off the new price because they make more money on the finance that goes with it. You can then push for the same discount when paying cash.

How to haggle when buying a car

We asked Pat Hoy, founder of Insider Car Deals, an independent specialist in new-car discounts and pricing, to give us his tips on how you can get the best deal when buying a new car and how to haggle for one effectively.

What’s your top tip for someone who hates haggling?

If you dislike haggling, reduce the need for it.

Decide the maximum you’re willing to pay (using the prices displayed in Which? car reviews as a guide), then say to a salesperson that you're happy to proceed if they're willing to match the price for the exact model and trim. This keeps the discussion simple and avoids drawn-out negotiations.

How would you deal with a salesperson refusing to budge on price?

If a salesperson won’t budge, stay calm and don’t take it personally.

Ask whether the price includes the best available dealer discount and all available manufacturer support. If it does, talk to a few other dealers for comparison.

Additionally, make it clear that you are prepared to walk away. That can often make a salesperson quickly change their stance.

Would you recommend accepting extras in place of a cash discount?

Prioritise a straight cash discount. Dealer-supplied extras such as paint protection or extended warranties often carry high margins, so the 'value' offered may cost the dealer far less than the discount you’re giving up.

Factory-fitted options you genuinely want are different – but only if you’d have chosen them anyway.

How can you tell when you’ve got the maximum available discount?

There’s no perfect way to know you’ve hit the maximum, but you can sense-check it.

If the offer is at, or close to, the car's price in the Which? review (which includes typical discounts for the base model), it’s already a strong deal. However, there may be a bit more discount available if you and the dealer can agree. Treat phrases such as 'that’s our limit' cautiously and use an independent benchmark to judge whether further movement is realistic.

Is there a good time of the year to pick up a bargain?

You’ll hear talk of end-of-month or end-of-quarter bargains, but it often depends on how well a model or dealer is performing. Early in the year can be competitive, as can the September plate change if targets are being chased. Also watch for manufacturer sales events, which sometimes bring stronger support.

Is it always better to pay in cash if you can afford it?

Not necessarily. Paying cash doesn’t automatically secure the best deal. A low-APR PCP offer with a strong finance deposit contribution can sometimes mean you pay less overall than the headline cash price. The key is to compare the total amount payable under each buying option before deciding.

What type of finance deal are you most likely to get the best deal with?

PCP (personal contract purchase) is usually where manufacturers concentrate most of their incentives, as it’s how the majority of new cars are bought. The strongest deals typically combine a low APR with a generous finance deposit contribution. Without both elements, a PCP offer may not be as competitive as it first appears.

Would you recommend part-exchanging a car as part of a deal?

Part-exchange is mainly for convenience, not maximum value. You’ll usually do better by agreeing the best price on the new car first, then discussing your current vehicle. That approach helps ensure the dealer offers a realistic market value. Selling privately can achieve more but involves extra time and effort.

What tricks will salespeople use to avoid giving you too big a discount?

Salespeople may say a model is 'selling out', that only stock cars qualify for bigger savings, or that a manufacturer's deposit contribution is the discount. Some claim they must contribute towards the cost of a PCP finance offer, limiting what they can reduce, or that the manufacturer won’t allow further discounting. These points can sometimes be true, but they’re also common negotiating lines. Sense-check against other dealers before accepting them at face value.
