New vs Used Cars: Which Should You Buy in 2026?

Buying a new vs used car is one of the biggest financial decisions you will make this year. You have probably found yourself bouncing between shiny showroom models and more affordable pre-owned alternatives, unsure which route actually gives you the best deal.

You are not alone. Over seven million used cars changed hands in the UK during 2025, compared with around two million new registrations. Clearly, both options have a strong pull.

This guide breaks down everything that matters: upfront cost, depreciation, finance, warranties, running costs, and the growing electric vehicle question. By the end, you will know exactly which option suits your budget, your lifestyle, and your priorities.

What Is the Real Cost Difference Between New and Used?

The price gap between a brand-new car and a used equivalent is often bigger than people expect. According to industry data, the average new car sold in the UK now costs around £34,000, while average used car prices sit roughly 40% lower.

That gap becomes clearer with real examples. A brand-new Suzuki Swift starts from £19,699. A two-year-old Swift with under 15,000 miles on the clock typically sells for around £13,000 to £15,000. That is a saving of up to £6,700 for a car that still looks, drives, and feels almost identical to the new version.

The same principle applies at the larger end. A new KGM Torres SUV with its 1,661-litre boot comes in at a competitive price for a mid-size SUV. Pick one up at two or three years old and you are looking at thousands less, with most of the same features and capability.

The bottom line: the used market consistently lets you get more car for your money. A budget that stretches to a base-spec new hatchback could land you a higher-trim or larger used model with premium features.

How Much Do New Cars Depreciate in the First Year?

A new car in the UK typically loses between 15% and 35% of its value within the first 12 months. By the end of year three, most vehicles have lost 50% to 60% of their original price. This first-year drop is the single biggest financial argument for buying used.

To put that in pounds and pence: if you buy a new car for £25,000, it could be worth as little as £15,000 after three years. That is a £10,000 loss. Buy the same model at three years old for £15,000, and it might be worth £11,000 after another three years of ownership. Your total depreciation cost drops to £4,000.

After the three-year mark, depreciation slows significantly. A car between five and seven years old might only lose 5% to 10% per year. This is why the two-to-four year sweet spot offers the best balance between a modern, well-equipped car and sensible finances.

Brand choice matters here, too. Suzuki models tend to hold their value well thanks to a strong reputation for reliability and sensible pricing. According to industry depreciation data, popular models like the Toyota Yaris Cross and Porsche Macan lose as little as 20% over three years, while some electric models lose over 60% in the same period.

Is Car Finance Cheaper on a New or Used Car?

New cars often come with manufacturer-backed finance deals, including 0% APR or heavily discounted rates. Suzuki, for example, has offered 0% APR on the Swift range. These deals make monthly payments on a new car surprisingly competitive, even though the total amount financed is higher.

Used car finance typically carries a higher APR. Lenders consider pre-owned vehicles a greater risk, so interest rates tend to be higher than manufacturer-subsidised new car deals.

However, the lower purchase price of a used car means you are borrowing less overall. Even with a higher rate, your monthly payments can still be very manageable. A used car costing £14,000 at 7% APR can work out to similar monthly payments as a new car at £20,000 on 0% APR, depending on the term.

The key takeaway: always compare the total cost of finance across the full agreement, not just the monthly figure or the headline rate. Factor in the deposit, the interest paid over the term, and any balloon payment at the end.

At Humphries & Parks, we offer finance options on both new and used cars, so you can compare both routes side by side with real numbers from our team.

Warranties and Peace of Mind: New vs Used

One of the strongest arguments for buying new is the manufacturer warranty. Every new Suzuki comes with a three-year/60,000-mile warranty as standard, extendable up to 10 years or 100,000 miles through their service-activated warranty programme. KGM offers a five-to-seven year warranty depending on the model, including the Torres EVX.

That level of cover gives genuine peace of mind. If something goes wrong in the first few years, the manufacturer picks up the bill.

Used cars from a reputable franchised dealer often come with their own warranty cover. At Humphries & Parks, our pre-owned vehicles go through a thorough inspection and preparation process before they reach the forecourt. Many nearly new models still carry the remainder of the original manufacturer warranty, which transfers to the new owner.

Buying privately or from an independent trader is where warranty cover gets thinner. Aftermarket warranties vary hugely in quality and coverage. If warranty protection is high on your priority list and you are buying used, choosing a franchised dealer with a strong aftersales reputation makes a real difference.

Running Costs: Insurance, Tax, and Fuel

The purchase price is only part of the story. Day-to-day running costs can tip the balance between new and used.

Insurance: New cars generally cost more to insure because their replacement value is higher. That said, newer models often come with advanced safety technology that can bring premiums down. Used cars in lower insurance groups are typically cheaper to cover, which is worth checking before you commit.

Road tax (VED): Newer cars, especially hybrids and EVs, often qualify for lower road tax bands. The full VED rates are published on GOV.UK. Older petrol and diesel cars with higher emissions will cost more to tax each year.

Fuel efficiency: Newer engines are generally more efficient. Suzuki's mild hybrid system, available across the Swift, Vitara, and S-Cross range, delivers strong fuel economy without the complexity of a plug-in. However, the fuel savings from a new car rarely offset the higher purchase price on their own.

Servicing and MOT: New cars are exempt from MOT testing for the first three years and typically need less maintenance in the early period. Used cars require an annual MOT and may need more frequent attention, though parts and labour for older models tend to be cheaper.

The Nearly New Sweet Spot: Best of Both Worlds?

A nearly new car is typically six to 18 months old with very low mileage, often under 5,000 miles. These are usually ex-demonstrators, pre-registered vehicles, or early returns from short-term finance deals.

Financially, nearly new cars sit in a compelling position. The first owner (often the dealership itself) absorbs the steepest depreciation hit. You get a car that looks, feels, and drives like new, with most of the latest technology and safety features, for significantly less than the full new price.

Many nearly new vehicles still carry the remainder of the manufacturer warranty, so you are not sacrificing peace of mind. The saving compared to buying the same model brand new can be several thousand pounds.

We regularly stock nearly new Suzuki and KGM models at our West Malling showroom. It is worth checking our used car listings regularly, as the best nearly new stock moves quickly.

What About Electric? New vs Used EVs in 2026

The electric vehicle market adds another layer to the new vs used question. New EVs like the Suzuki e Vitara (from £26,249) and the KGM Torres EVX, with its 287-mile range and 73.4 kWh battery, are now genuinely practical options for UK families.

Used EVs can offer substantial savings. A two-or-three-year-old electric car often costs 40% to 60% less than it did new. Some first-generation models have lost over 70% of their value in three years, according to depreciation analysis from Carmoola and Brego.

But there is a reason for those steep discounts. Battery technology improves rapidly, meaning older EVs offer shorter range and slower charging than current models. Battery health is also harder to assess than engine condition, which adds a layer of risk for used EV buyers.

For most people buying their first electric car, a new model with a full battery warranty and the latest range and charging technology offers the safest entry point. If you want to dip a toe into electrification without the commitment, a used or new hybrid is a lower-risk alternative.

Should I Buy New or Used? A Quick Decision Guide

There is no single right answer. The best choice depends entirely on your circumstances. Here is a straightforward way to think about it:

Choose used if: you want the most car for your budget, you drive high mileage (where depreciation matters less than running costs), or you are saving for other big financial goals. A well-chosen used car from a trusted dealer is one of the smartest ways to spend your money.

Choose new if: you want the latest safety technology and infotainment, a full manufacturer warranty with zero history risk, or you plan to keep the car for five or more years. Buying new and holding long-term spreads the depreciation cost over a longer period.

Choose nearly new if: you want modern features and remaining warranty cover without paying the full new premium. This is often the financial sweet spot for drivers who want the best of both worlds.

Whichever route you take, focus on the total cost of ownership rather than just the sticker price. Add up the purchase price, finance costs, insurance, tax, fuel, and likely depreciation over your expected ownership period. That total figure tells you the real cost of each option.

Why Buy From a Local Dealer You Can Trust?

Whether you choose new or used, where you buy matters just as much as what you buy. A franchised dealer with a strong local reputation gives you something online-only platforms and private sellers simply cannot: accountability, aftersales support, and a real person to call if you need help.
