Nearly-new, used or new: which is the best buy

Buying a car almost always comes down to three routes: brand-new from the factory, nearly-new (in Italy, km 0) and used. On paper they look like versions of the same thing, but underneath sit real differences in price, warranty, depreciation and freedom of choice, differences that can add up to several thousand euros. Understanding what truly separates these options is the surest way to avoid overpaying and to drive home the car that actually fits your life.

What a km 0 car really is

The term km zero is everyday language in Italy, but it is often misunderstood. A km 0 car is a brand-new vehicle, never really driven, that has already been registered by the dealer or the manufacturer. Legally, then, it is not new: it counts as used, even though the odometer shows only a few dozen kilometres, picked up moving it from the warehouse to the showroom floor. Dealers register these cars to hit the sales targets set by carmakers, then resell them at a modest discount. Do not confuse a km 0 with an ex-company or ex-rental car, which usually carries more mileage and a year or more of age.

Price: how much you actually save

The clearest advantage of a km 0 car is price. Against the list price of the identical new model, the discount is typically 10 to 25 per cent, sometimes more on ready-to-deliver trims the dealer is keen to clear. A new car starts at full list price: you can negotiate, but the margin is tighter and often tied to the manufacturer's own financing. Used is the most elastic category of all: the price depends on age, mileage, condition and history, ranging from almost-new down to very low figures for cars with several years behind them. As a rule, for the same model the spend rises in this order: used, km 0, new.

Warranty: watch when the clock starts

This is the detail many buyers miss. By law, anyone buying from a professional seller (a dealer or trader) is entitled to the 24-month legal warranty of conformity set out in the Italian Consumer Code (Codice del Consumo): it is compulsory, free, and covers faults already present at delivery. On a new car, those 24 months start from the day it is handed to you. On a km 0, the manufacturer's warranty runs from the registration date: if the car was registered six months earlier, you have roughly 18 months left, not 24. On a used car the legal warranty is still 24 months, but between a professional and a private buyer it can be cut to 12 months by written agreement. Before signing, always ask for the registration date and read carefully what the warranty actually covers.

Depreciation: where your money goes

Depreciation is the invisible cost that hits hardest. A new car loses a large slice of its value the moment it is registered and leaves the forecourt: estimates put it around 9 to 11 per cent straight away, roughly 20 per cent within the first year, and up to about 40 per cent over three years. Buy new and you pay that first hit in full. Choose a km 0 and you dodge almost all of it: you take a practically new car after someone else, the dealer, has absorbed the first registration. A used car, meanwhile, has already shed much of its depreciation: the older the car, the flatter the curve and the less it loses each following year. Watch out, though, for penalised engines: older diesels, subject to bans in ZTL zones and low-emission areas, lose value faster.

The costs that are the same for everyone

Some expenses do not care whether the car is new, km 0 or used, but you should budget for them. The passaggio di proprietà (ownership transfer) is paid every time the car changes hands: the fixed national portion is around 101.20 euros (ACI fees, Motorizzazione charges and stamp duties), plus the IPT, the provincial registration tax, which starts near 150 euros for lower-powered cars and rises with kilowatts, with surcharges of up to 30 per cent set by each province. A new car registered directly to you skips the transfer but still pays IPT at first registration. Then come the recurring costs that fall on everyone alike: the bollo, the regional ownership tax based on power and emissions class; the revisione, the roadworthiness test due four years after first registration and every two years after that; and insurance. A newer car generally costs less to maintain and will not send you straight to the revisione.

Who each option suits best

New suits the buyer who wants to personalise everything (engine, trim, colour), keeps the car a long time (eight to ten years, so depreciation is diluted), wants the latest technology, or is chasing manufacturer financing and incentives. Remember that some state or regional bonuses are tied to your ISEE (the household income indicator) or to scrapping an old car, and they change over time, so check them at the moment of purchase. Km 0 is the most balanced choice for someone who wants an almost-new car, a recent model, available immediately and without the first depreciation hit, accepting a pre-decided trim and a few months less warranty. Used is ideal on a tight budget, for a family's second car, or for newly licensed drivers (neopatentati), who can learn on a cheaper vehicle while minding the power limits that apply to a patente B in the first years. In every case, checking the car's history and service record stays essential.

The takeaway: how to decide

There is no universally right option, only the one that is right for you. Start with three questions. How much do you want to spend now, and how much can you afford to lose to depreciation? How many years will you keep the car? How much do you value having the newest model and the longest possible warranty? If you prize immediate savings without giving up a practically new car, km 0 is often the best compromise. If you plan to keep the car for years and want it built to order, new pays off over time. If budget rules, a well-kept used car is hard to beat. Comparing several listings, for instance browsing what is on VendiVoce, helps you build a realistic sense of prices before you start negotiating.
