When buying a used car, the terms second-hand, pre-owned and Km 0 often cause confusion.
The main difference between them lies in their previous use, the condition of the vehicle, the warranty and the price, which directly influences the total cost and the level of risk involved in the purchase.
Second-hand vehicles
A second-hand vehicle, also called used cars, is one that has had one or more previous owners and has already been used normally for a more or less long period of time.
Advantages
- Lower price than a pre-owned or zero-mileage car.
- Wide range of models, versions and years.
- Greater room for negotiation, especially between private individuals.
Disadvantages
- Greater mechanical and aesthetic wear and tear.
- Vehicle history not always clear (maintenance, accidents, intensive use).
- Possible repairs in the short or medium term.
Warranty
- Between private individuals: no legal warranty, except for hidden defects.
- At dealerships or professionals: minimum legal warranty of 1 year in most European countries.
Price and associated costs
- This is the most economical option in terms of purchase price.
- Most common additional costs:
- Immediate maintenance.
- Unforeseen repairs.
- Possible replacement of tyres, brakes or timing belt.
- Certificate of Conformity, if you need to import it into your country and register it.
Pre-owned vehicles (Used cars)
Pre-owned vehicles are usually relatively recent cars with low mileage and in very good condition. They typically come from:
- Renting
- Leasing
- Company vehicles
- Demonstration cars
Advantages
- Good balance between price and overall condition.
- Lower mileage than a traditional second-hand car.
- More controlled history, especially if it comes from a professional.
Disadvantages
- Higher price than a conventional second-hand car.
- Less room for negotiation.
- Less customisation compared to a new car.
Warranty
- Sold by professionals, it usually includes:
- 1-year legal warranty.
- In many cases, extended commercial warranty (12–24 months).
Price and associated costs
- Price between second-hand and 0 km.
- More predictable costs:
- Less likelihood of immediate repairs.
- Maintenance less frequent.
Zero-mileage vehicles
A zero-mileage vehicle is a car that has already been registered by the dealership, but with minimal or no use. It has had no real owners, although legally it is not ‘new’.
Advantages
- Practically new condition.
- Immediate delivery (no manufacturing time).
- Lower price than a brand new car.
Disadvantages
- The configuration cannot be customised.
- It is already registered, which affects the warranty date and the future resale value.
Warranty
- Official manufacturer's warranty, same as a new car:
- Normally 2 or more years, depending on the brand.
- Starts from the date of first registration.
Price and associated costs
- Higher price within the used car market.
- Lower initial costs: No immediate maintenance, lower risk of breakdowns and taxes and insurance similar to those of a new car.
Quick comparison
- Cheaper: second-hand
- Best value for money: used
- Lower risk and better warranty: 0 km
Which is best?
The choice depends on your budget, intended use and the level of peace of mind you are looking for:
- If you prioritise price, second-hand is the most affordable option.
- If you are looking for safety without paying the price of a new car, a used car is usually the most logical alternative.
- If you want a new car with a discount and maximum warranty, a zero-mileage car is the closest option to a new vehicle.
In all cases, checking the history, actual condition and warranty terms is key to avoiding surprises and correctly calculating the total cost of the purchase.
Frequently Asked Questions
We answer the most frequently asked questions about used, second-hand and zero-mileage vehicles.
Is a zero-mileage car legally considered new?
No. Although it is practically new, a zero-mileage vehicle is already registered, usually in the name of the dealership.
Therefore, it is not legally considered new, even if it retains the manufacturer's official warranty.
Is it safer to buy a pre-owned car than a second-hand car?
In general, yes. Pre-owned cars are usually newer, with fewer kilometres and a more controlled history, especially when purchased from professionals.
This reduces the risk of breakdowns and usually includes a clearer warranty.
Which option has the lowest total cost in the long term?
It depends on the condition of the vehicle and its intended use, but usually:
- A second-hand car is cheaper to buy, but can generate more maintenance costs.
- A zero-mileage car has a higher price tag, but fewer unexpected costs.
- A pre-owned usually offers the best balance between price, warranty and future costs.
Does the warranty cover the same in all cases?
No. Coverage varies:
- For second-hand cars sold between private individuals, protection is very limited.
- For pre-owned cars and zero-mileage cars sold by professionals, the warranty is more comprehensive and clear.
- Zero-mileage cars come with the official manufacturer's warranty, which is usually the most comprehensive.
Can any of these types of vehicles be financed?
Yes. Both pre-owned cars and zero-mileage cars can usually be financed, although the best conditions usually apply to used and zero-mileage vehicles.
