Km 0 car or used: which is better in 2026
Discounts from 10% to 35%, warranties that start on different dates, ownership transfer fees: how to compare a km 0 car with a recent used one and choose by budget, brand and ownership time.

If you are weighing a km 0 car versus a used car in Italy, you are really choosing between two kinds of discount: the dealer's discount on a nearly new, pre-registered car, or the depreciation someone else has already absorbed on a used one. Which wins depends on your budget, the brand and how long you plan to keep the car. This guide lays out the numbers, the warranty rules and the checks to make [1][2].
What a km 0 car actually is
A km 0 car (zero kilometres) is a vehicle that has already been registered, usually by the dealer or the manufacturer, and is sold with almost no mileage. Legally it is a used car even though nobody has really driven it. Two practical consequences follow: the registration papers already show a first owner (the dealer), and your purchase requires an ownership transfer with its own fees [3].
They exist because dealers register cars to hit sales targets and then clear them with discounts. The trade-off is limited choice: colour, trim and options are whatever is on the lot.
How much you save compared with a new car
The sources suggest discounts vary widely, from about 10% up to 35% off list price depending on model and timing [1][2]. Brand matters most:
- Brands that hold their value (Toyota, Hyundai, Kia, Dacia): smaller discounts, because demand is strong even for new cars.
- Brands with stock to clear: bigger discounts, but usually faster depreciation later.
Example: on a car listed at 25,000 euros, a 15% discount is worth 3,750 euros and a 25% discount 6,250. Subtract the ownership transfer costs (provincial tax, ACI and PRA fees, stamps) and compare the offer with a manufacturer promotion on the new model, which often includes similar discounts.
Warranty: where it gets confusing
There are two separate warranties:
- The seller's legal warranty: for consumers it is 24 months and starts at delivery, not at registration. For used goods the parties may agree in writing to a shorter term, but not below 12 months [3][4]. Make sure it is stated in the contract.
- The manufacturer's warranty: it starts at first registration. If the car sat on the lot for six months, six months are already gone [3].
Example: a car registered in March and delivered in May. The seller's warranty runs 24 months from May, while the manufacturer's coverage has already used two months [3]. Some manufacturer warranties also require scheduled servicing, so ask how the car was looked after while it sat unsold.
Sources are not fully consistent on the exact terms, so read the contract and get the registration date, remaining warranty months and conditions in writing.
Why a recent used car can beat a km 0
The used market is far bigger: according to ACI data cited by Money.it, in the first quarter of 2026 Italy sold 179 used cars for every 100 new ones registered, and the average list price of a new car has passed 36,000 euros [2]. On a tight budget a 2-3 year old used car often offers:
- More choice in versions, colours and equipment.
- Depreciation already absorbed: the steepest drop comes in the first years, and it is especially sharp on electric cars [1].
- Lower prices for similar equipment, in exchange for a shorter manufacturer warranty.
If you keep the car 8-10 years, the depreciation gap shrinks and a long warranty matters more. If you resell after 3-4 years, what counts is how much you paid against the residual value.
A quick decision grid
- Long ownership, full warranty wanted: km 0 from a brand that holds value, with plenty of warranty left.
- Tight budget, high mileage: a 2-4 year old used car with documented servicing.
- You want to pick colour and options: neither; consider a configured new car.
- Electric car: watch the early depreciation; a recent used one may be the rational buy [1].
What to check before you sign
- First registration date and remaining warranty months.
- Real mileage: only transport and delivery kilometres should show.
- The full quote: price, on-road charges, ownership transfer and any mandatory packages.
- Lot damage: hail, scratches, dents from transport.
- Paperwork: registration document, certificate of conformity and service invoices if the car sat for long.
- Comparison: look for the same car as a 1-2 year old used one and as a new car on promotion.
The takeaway
A km 0 makes sense when the discount is high and plenty of warranty remains; a recent used car makes sense when the final price and the choice matter more. Either way, compare three offers, get everything in writing and do not stop at the sticker price. If you are selling your current car to move into a km 0, remember that the trade-in valuation affects your total as much as the discount.
