The 5 scams to avoid when buying a used car
Discover the 5 common scams in Switzerland and the RG Automotive checklist to buy a used car with peace of mind.

1. The tampered odometer
A vehicle displaying 80'000 km may actually have 150'000. This distorts the price and increases the risk of premature breakdowns.
Our advice: Compare the service book and invoices. An inconsistency = warning sign.
2. Concealed defects
Repainted rust, disabled warning lights, polished headlights on the surface… some sellers know how to hide problems.
Watch out for: Always test the vehicle on different types of roads for at least 20 minutes.
3. Hidden costs
A low price can hide CHF 2'000.– or more in repairs: tyres, brakes, air conditioning…
Concrete example: a car listed at CHF 12'000.– can cost CHF 14'200.– after tyre and brake replacement (+CHF 2'200.–).
4. Dubious imports
Vehicles imported without history: undeclared accidents, missing maintenance, uncertain origin.
Did you know? A complete service book increases resale value by 10 to 15%.
Our advice: before any purchase, verify the vehicle's chassis number (VIN) on a specialized platform like CarVertical. You will find the complete history there: accidents, mileage, maintenance, recalls. A check that costs a few dozen francs can save you a loss of several thousand.
5. Seller pressure
"Another buyer is coming!" → classic technique to push you to buy without checking.
Our advice: never give in to pressure. If the deal is good, it will still be good tomorrow.
