The decision in brief
Whether a used or a new car is the more economical choice rarely comes down to the price tag. Three factors matter: how long you plan to keep the car, how much and for what you drive, and which equipment you actually need. A new car loses most of its value in the first years; a well-maintained used car has already absorbed that loss. In return, a new car offers the full manufacturer warranty, current technology and free configuration.
The best car is not the cheapest one, but the one that costs least over your planned ownership period and forces no compromises in daily use.
When a used car is the better choice
- You want to limit the purchase cost without giving up a reasonably modern vehicle.
- You need a car quickly and cannot wait months for a factory order.
- For you, the car is a practical tool rather than a status symbol.
- Cars with the equipment you are looking for are already on the market.
- You drive relatively little and do not want capital tied up in rapid depreciation.
Cars around two to five years old with a complete service history are particularly interesting. Their technology is usually still current, but the steepest depreciation is behind them. With older cars the risk of major repairs increases, which you should factor into your calculation.
When a new car makes more sense
A new car pays off mainly when your requirements are precise: a specific drivetrain, towing capacity, particular driver assistance systems or a configuration for family and work that is hard to find on the used market. If you keep a car for a long time, say eight years or more, the initial depreciation is spread across many years. Add the full factory warranty, a known history and, for electric cars, the latest battery and charging technology.
Beware of short ownership periods
If you only plan to keep a car for two or three years, a new car means carrying most of the depreciation yourself. In that case, compare carefully with a nearly new used car or a lease with a realistic mileage allowance.
Side-by-side comparison
| Criterion | Used car | New car |
|---|---|---|
| Purchase | Usually a much lower entry price | Higher entry price |
| Depreciation | Partly already absorbed | Steepest in the first years |
| Warranty | Depends on age, mileage and dealer | Full factory warranty from delivery |
| Availability | Often immediate | Weeks to months, depending on model |
| Equipment | Existing configuration | Freely selectable |
| History | Must be checked | Known |
| Roadworthiness test (MFK) | May be due soon | Usually only after four years |
Checklist for buying used
- Check the service book and invoices: was maintenance done according to the manufacturer's schedule?
- Look at the vehicle registration document: date of first registration, number of owners and last roadworthiness test.
- Take a test drive, including on the motorway and with a cold engine.
- For higher prices, have an independent used-car inspection done at a garage or by a motoring club.
- Put warranty and liability terms in writing and read the purchase contract carefully.
- For electric cars, ask for evidence of the battery's condition.
Liability in the purchase contract
Under the Swiss Code of Obligations the seller is in principle liable for defects. In the used-car trade, however, this liability is often excluded with wording such as "as seen and test-driven", especially in private sales. Check exactly what is excluded, and get any dealer warranty, with its scope and duration, in writing.
Calculating total cost realistically
Compare the cost over the whole planned ownership period, not purchase prices. That includes depreciation, insurance, cantonal vehicle tax, servicing and repairs, tyres, energy and, where relevant, interest on a lease or loan. A new car may have lower repair costs and consumption; a used car ties up less capital. Which side wins depends on the individual case.
A simple method: estimate the resale value at the end of the ownership period for both options, subtract it from the purchase price and add the running costs. Valuation portals and dealer quotes help with the estimate, but only provide guide values.
