New car, km 0 or used: which is the better deal in 2026?

---

Summary:

• A new car offers full warranty and complete customisation, but loses value significantly in the first few years.
• A km 0 (never-owned) car is often the smartest choice: near-new condition at a discounted price, with most of the manufacturer warranty still intact.
• A used car delivers the best value per euro spent, provided you buy from a verified seller and check the vehicle's history carefully.

Every car buyer eventually faces the same question: is it better to buy new, km 0 or used? There is no one-size-fits-all answer — the right choice depends on your budget, driving habits and priorities. This guide from CarPulse breaks down all three options with their advantages, drawbacks and the specific situations where each makes sense. If you are already exploring the Italian market, you can browse used and km 0 listings on CarPulse.it to get a realistic picture of current market prices.

New car: what you are actually buying

A new car is a vehicle with no previous owners, ordered through the manufacturer's dealer network and delivered exactly to the buyer's specification — colour, trim level, engine, options. The manufacturer's warranty covers it in full, typically for two to five years or a set mileage limit, with service backed by the official dealer network.

The primary advantage is certainty: zero kilometres, no history to investigate, complete traceability. The downside is the price. Buying new means paying the maximum market value for that model, and depreciation begins the moment you sign the contract — even before you drive off the forecourt. A significant portion of the vehicle's value can evaporate in the first few years of ownership.

Who should choose new? Buyers who want a specific configuration the used market cannot supply, those with specific business requirements (VAT recovery, fleet benefit schemes), or anyone who needs the absolute peace of mind of an untouched vehicle.

What is a km 0 car — and how it differs from used

The term km 0 (short for "chilometri zero", literally zero kilometres) refers to a car that has been registered but never sold to a private customer. Italian dealerships register these vehicles in their own name — as demonstration models or to hit the monthly volume targets set by the manufacturer — and then offer them for sale a few months later, typically with fewer than 500–1,000 km on the clock.

From a legal standpoint, a km 0 car is technically used the moment it is registered, regardless of mileage. This has two important practical consequences:

• Lower price: the discount off the new list price can be meaningful — often several thousand euros depending on the model and the timing.
• Reduced but often still substantial warranty: the manufacturer warranty runs from the original registration date. If the car was registered six months ago and the manufacturer offers a three-year warranty, you still have two and a half years of cover remaining.

A km 0 is often regarded as the ideal middle ground: practically new, discounted, and still well covered under warranty. The only trade-off is that you cannot customise it — you choose from existing stock — but that stock typically covers the most popular variants.

The used car: smart savings with the right approach

A used car is any vehicle that has had one or more private owners. The Italian second-hand market is broad and offers an enormous variety of models, vintages and price points. It is the preferred choice for buyers who want to maximise value for every euro they spend.

The benefits of buying used are straightforward:

• Lower purchase price: you can access segments and trim levels that would be out of reach if bought new.
• Depreciation already absorbed: the steepest years of value loss are already behind the vehicle. Buying a car that is three or four years old means you pay less and, proportionally, lose less over the years ahead.
• Generally lower insurance costs: a vehicle with a lower market value typically costs less to insure against theft or damage.

The main risks with used cars relate to the vehicle's history: tampered odometers, undisclosed accidents, neglected maintenance. This makes it essential to check the full service history before committing to a purchase. Before making an offer, use the fair price checker on CarPulse.it to confirm whether the asking price is in line with the market.

Depreciation: the factor that changes everything

Depreciation is probably the most underestimated factor in a car purchase decision. A new car experiences its sharpest drop in value during the first years of ownership: the decline relative to the purchase price can be very significant. This is not opinion — it is a structural feature of the automotive market, one that systematically rewards used-car buyers on a pure financial basis.

A km 0 car, having already passed through the registration event, has absorbed the very first step of the depreciation curve and therefore offers an immediate advantage over a brand-new equivalent. A used car with several years of age has passed the steepest phase, and annual value loss tends to flatten out.

This does not mean a used car is always cheaper in absolute terms: potential maintenance and repair costs increase with age, and a very cheaply bought used car that requires frequent work can end up costing more than expected over the long run.

Warranties and risks: what each option covers

The warranty is one of the most tangible differences between the three options:

• New car: full manufacturer warranty (typically 2–5 years), official dealer service network, optional extended warranty available.
• Km 0: residual manufacturer warranty from the registration date. For recently registered vehicles, the remaining cover can still be very generous.
• Used car: mandatory legal warranty of 12 months (reducible to 6 months by agreement for vehicles older than 12 months) when purchased from a professional dealer. Private sales carry no automatic legal warranty.

For used cars bought from private sellers, it is therefore critical to use platforms that provide some level of seller verification. On CarPulse.it you can search verified seller listings, filtering by model, year and price range, with access to vehicle information before contacting the seller.

Which to choose based on your budget

A simplified practical framework:

• Tight budget (under €10,000): the used market is the only realistic option. Focus on reliable models with documented service history and a valid roadworthiness test. Always verify market value before negotiating.
• Mid-range budget (€10,000–€25,000): the choice opens up. Km 0 becomes very attractive in this bracket — you can find B- and C-segment cars registered just months ago at worthwhile discounts. A two-to-four-year-old used car is equally valid if the vehicle history is transparent.
• Higher budget (above €25,000): all three options are viable. New makes sense if you need a specific configuration or plan to keep the car for many years. Km 0 remains a strong value play even at this level. Premium used (luxury or sports cars a few years old) can offer exceptional value.

Regardless of budget, the first step should always be to check the fair market value of the vehicle you are considering. The CarPulse price valuation tool lets you do this for free in seconds.

Conclusion

There is no universally "right" answer between new, km 0 and used: there is only the right answer for your budget, your needs and your risk tolerance. Km 0 is often the most balanced choice for buyers who want near-new quality at a real discount. Used wins on pure economics when purchased carefully from a reputable source. New makes sense when full customisation and a complete warranty are worth the premium.
