Car buying glossary:
30 terms explained
From Topzoekertje to TÜV: this glossary explains 30 terms you meet when buying, selling or flipping a used car in Belgium, the Netherlands and Germany. Every definition is short, factual and readable on its own, so you can jump straight to the term you need.
APK (Dutch periodic inspection)
The APK (Algemene Periodieke Keuring) is the legally required periodic vehicle inspection in the Netherlands. A new petrol car is first inspected after four years, then every two years and annually from eight years; diesel and LPG cars are inspected earlier and more often. A recent APK says something about the minimum technical condition of a used car but nothing about wear or upcoming maintenance.
Autokeuring (Belgian inspection)
The autokeuring is the mandatory technical inspection of vehicles in Belgium, carried out by approved inspection centres. Passenger cars are inspected periodically from the age of four and when a car is sold to a private buyer a second-hand inspection is required before the new owner can register it. The inspection certificate also lists remarks and re-inspections, useful information when buying.
BIV (Belgian registration tax)
The BIV (belasting op de inverkeerstelling) is the one-off Belgian registration tax you pay when a vehicle is registered in your name. In Flanders the BIV is calculated from CO2 emissions, euro standard, fuel and age among other factors; in Brussels and Wallonia mainly from engine power and fiscal horsepower. For older cars the BIV drops to a minimum amount.
BPM (Dutch registration tax)
BPM is the Dutch purchase tax due when a car is registered in the Netherlands for the first time. For passenger cars the amount depends mainly on CO2 emissions. When importing a used car you also pay residual BPM, calculated from the depreciation of the vehicle.
Car alert
A car alert is an automatic notification you receive as soon as a new listing matches your search criteria, such as brand, price, year and mileage. Speed is decisive here because sharply priced cars often sell within hours. Autoflip sends such alerts via Telegram within seconds of publication and monitors 2dehands.be, Marktplaats.nl, AutoScout24 BE and NL and Mobile.de at the same time.
Car flipping
Car flipping is buying a car below market value in order to resell it at a profit. The profit comes from reacting fast to sharply priced listings, small cosmetic fixes and good negotiation. Anyone flipping cars structurally counts as a trader under the law and must register and pay taxes; occasionally selling a car at a profit is allowed as a private person.
Car-Pass
The Car-Pass is a mandatory Belgian document that shows the recorded odometer readings of a vehicle over time. At every sale of a used car to a private buyer in Belgium the seller must hand over a recent Car-Pass. It is compiled from readings reported by garages and inspection centres and is the main protection against odometer rollback.
COC document
The COC document (Certificate of Conformity) is the manufacturer's declaration that a vehicle complies with its European type approval. You need it to register an imported car in Belgium or the Netherlands. Many cars have the COC among the on-board documents; if it is missing you can request it from the manufacturer or importer for a fee.
Current market value (dagwaarde)
The current market value (dagwaarde) is what a car is worth today, taking into account age, mileage, condition and demand. Insurers use it to determine the payout after a total loss or theft. For buyers and sellers it is the reference point for judging whether an asking price is realistic.
CVT
A CVT (continuously variable transmission) is an automatic without fixed gears that adjusts its ratio steplessly, usually via a belt or chain between two pulleys. It drives smoothly and efficiently but engine revs can feel disconnected from speed when accelerating. The e-CVT in Toyota hybrids is technically a planetary gearset without a belt and is known to be very reliable; conventional CVTs need strict maintenance with the correct fluid.
Dagtopper (pinned daily ad)
A Dagtopper is a paid daily promotion on 2dehands.be and Marktplaats.nl that pins a listing to the very first position in the search results for a day. The pinned ad appears on top under every sort order, including sorting by date. The top result is therefore often not the newest listing.
DSG
DSG (Direct-Shift Gearbox) is the Volkswagen Group's dual-clutch automatic, used in Volkswagen, Audi, Seat and Skoda models among others. It shifts fast and efficiently because the next gear is already engaged on the second clutch. On older examples watch for the known weak points: the mechatronic unit and clutch wear on the dry seven-speed version; regular oil changes matter on the wet-clutch variant.
Kaufvertrag
A Kaufvertrag is the German purchase contract you sign when buying a car in Germany, for example via Mobile.de. Between private parties cars are almost always sold with a clause excluding any warranty ('gekauft wie gesehen'). Use a standard contract such as the ADAC model, verify the seller's details and have the mileage and known defects written explicitly into the contract.
LEZ (low-emission zone)
An LEZ (low-emission zone) is a city zone where polluting vehicles are banned or only allowed against payment. Antwerp, Ghent and Brussels operate such zones based on euro standard and fuel; Dutch cities have comparable environmental zones. Before buying an older diesel, check whether it is still allowed in the cities you need because the rules tighten step by step.
List price (catalogusprijs)
The list price (catalogusprijs) is the official new price of a car including options and taxes at the moment of first registration. In the Netherlands it is the basis for the private-use tax addition on a company car. When buying used, the list price mainly helps you see how much a car has depreciated compared to new.
Margin car (margin scheme)
A margin car is a used car sold by a dealer under the VAT margin scheme, where VAT is only paid on the dealer's profit margin instead of on the full sale price. This applies to cars the dealer bought without VAT, usually from a private owner. As a buyer you cannot reclaim any VAT on a margin car, which mainly matters for businesses; for private buyers it usually makes little difference.
NAP odometer reading
The NAP odometer reading (Nationale Auto Pas) is the officially registered mileage history of a vehicle in the Netherlands, maintained by the RDW. Garages and inspection stations report readings at maintenance and APK inspections, after which the RDW judges whether the progression is logical. Before buying a used car in the Netherlands you can check this history for free via the RDW.
Occasion (used car)
An occasion is simply a used car offered for sale, whether by a dealer or by a private seller. The term is common in the Netherlands, Belgium and France and says nothing about age or condition. Anything from a nearly new executive car to a car with 300,000 km on the clock counts as an occasion.
Odometer fraud
Odometer fraud is illegally rolling back a car's odometer to make it look younger and more valuable. In Belgium you check the history via the Car-Pass and in the Netherlands via the RDW's NAP registration; for imports from other countries such a closed system is often missing. Therefore always compare the odometer with the service book, inspection reports and the wear on the steering wheel, pedals and seats.
Oldtimer (classic car)
An oldtimer is a car old enough for special classic-vehicle status. In Belgium a car can get an O registration from 30 years old, with limited use and lower taxes; in the Netherlands the road-tax exemption only applies from 40 years. Always check the rules for your region or country before buying because age limits and conditions differ.
Particulate filter (DPF)
A particulate filter (DPF) is the filter in a diesel's exhaust system that captures soot particles and periodically burns them off during regeneration. Many short city trips prevent that regeneration and clog the filter; a replacement easily costs more than a thousand euros. Removing a DPF is illegal and the car will fail inspection, so when buying a used diesel check whether it regularly drove longer distances.
Private seller vs dealer
Private seller versus dealer indicates who is selling the car: a private person or a professional trader. From a dealer you get statutory consumer warranty and usually a higher price; from a private seller you generally buy cheaper but without warranty, although the seller remains liable for hidden defects. On listing sites the distinction is not always clear because some traders advertise as private sellers.
Road tax (verkeersbelasting)
Road tax is the annual tax you pay to drive a vehicle on public roads. In Belgium it is calculated from fiscal horsepower or engine displacement and differs per region; in the Netherlands it is called motorrijtuigenbelasting and depends mainly on weight, fuel and province. Factor in this fixed cost before buying a heavy or older car.
Saved search
Saving a search means storing your search filters so a platform notifies you about new results. The built-in saved searches of 2dehands, Marktplaats and AutoScout24 often send notifications batched or with delay. Buyers who want to be faster than others use a real-time alert service that checks the platforms continuously.
Timing belt vs chain
The timing belt or timing chain connects the crankshaft to the camshaft and keeps valves and pistons synchronised. A belt must be replaced preventively, usually between 60,000 and 120,000 km or every four to six years, a job costing several hundred euros; a chain is in principle designed to last the life of the car but can stretch on some engines. Always ask when the belt was last replaced because a snapped timing belt often means engine damage.
Topzoekertje (top ad)
A Topzoekertje is a paid ad placement on 2dehands.be and Marktplaats.nl that keeps a listing at the top of the search results regardless of its publication date. As a result page 1 is often filled with ads that have been online for days or weeks. To find genuinely new listings you need to look beyond the first page or sort by date.
Torque converter
A torque converter is the hydraulic coupling in a classic automatic that connects the engine to the gearbox through fluid instead of a clutch plate. This makes pulling away and shifting particularly smooth and the system is considered very durable. Modern torque-converter automatics such as the widely used eight-speed units are also efficient; on older cars regular fluid changes are the main point of attention.
TÜV
TÜV is the German inspection organisation that carries out the mandatory periodic vehicle inspection (Hauptuntersuchung or HU). Passenger cars in Germany must be inspected every two years and a new car for the first time after three years. When a Mobile.de listing says 'TÜV neu' or 'HU neu' the car has just passed, which is a useful indication of technical condition when importing.
Vrijwaringsbewijs (indemnity certificate)
A vrijwaringsbewijs is the Dutch document proving that a vehicle is no longer registered in your name. You receive it when the registration is transferred to a new owner or when the car is dismantled or exported. From that moment you are no longer liable for fines, taxes and the insurance obligation, so keep it safe after selling.
Youngtimer
A youngtimer is a car of roughly fifteen to thirty years old, too young for classic status but old enough to be seen as a future classic. In the Netherlands the term also has a tax meaning: for cars of fifteen years and older the private-use addition is calculated on the current market value instead of the original list price. Well-maintained youngtimers often hold their value better than ordinary used cars.
