The Walloon automotive market is entering a period of fiscal transition. Wallonia has announced a reform of its automotive taxation with the introduction of a vignette and a revision of the circulation tax, measures planned as part of the 2027 budget. For a buyer in Naninne or the Namur region, the price displayed on the windshield no longer tells the whole story.
The real cost of a vehicle now depends on its engine type, its emission standard, and taxes that did not exist two years ago.
Walloon tax reform and engine choice in Naninne
The vignette announced by the Walloon government would be differentiated based on the engine type and emission standard of the vehicle. Contrary to what many assume, electric cars would not be exempt from this vignette. This changes the game for anyone comparing a thermal model to an electrified model based solely on the catalog price.
The announced reduction in the circulation tax will not necessarily offset the cost of the vignette for every driver. The balance depends on the vehicle profile. A buyer who is torn between a recent gasoline city car and an older plug-in hybrid SUV can no longer rely solely on the “green” or “thermal” labels to estimate their annual costs.
The exact timing and details of these measures remain to be confirmed at the time of purchase. A locally established automotive professional keeps track of these regulatory developments and can project the total cost of ownership over several years, incorporating taxes, insurance, maintenance, and consumption. This is precisely the type of advice that a garage Autos Minne in Naninne can provide during a discussion about vehicle choice, as the answer varies from one driver to another.
Car-Pass and battery: what the used document reveals (or not)
For used vehicles, the Car-Pass remains the reference document in Belgium. Since October 23, 2025, the health status of the battery can be included on the Car-Pass for electrified vehicles, provided that the manufacturer has communicated this data.
The conditional is intentional. The presence of this information is not guaranteed for all models. Some manufacturers systematically transmit battery degradation data, while others do not. A Car-Pass without a battery mention does not mean that it is faulty, but that no data has been provided by the manufacturer.
What to check when the Car-Pass is silent on the battery
When this data is missing, an independent battery diagnosis becomes the only reliable way to assess the remaining capacity. A professional garage equipped with manufacturer diagnostic tools can measure the SOH (State of Health) and provide a quantified report. Without this test, buying a used electrified vehicle is akin to estimating the wear of a diesel engine without ever opening the hood.
Points to examine beyond the Car-Pass include several concrete elements:
- The number of fast charge cycles experienced by the battery, which accelerates the degradation of lithium-ion cells more than slow home charging
- The maintenance history specific to the high-voltage system, distinct from conventional mechanical maintenance (brakes, tires, filters)
- The correspondence between the range announced by the manufacturer and the actual range measured during a test drive, ideally on a mixed city-highway route
Compare the total cost of ownership before signing
The classic reflex is to compare financing monthly payments or the purchase price. This approach ignores half of the equation. The total cost of ownership over five years can vary significantly between two vehicles listed at the same price.
Items that the purchase price does not show
The maintenance of a hybrid or electric vehicle structurally differs from that of a thermal vehicle. Fewer mechanical wear parts (no clutch, regenerative braking that spares the pads), but specific costs: replacement of the battery pack coolant, software updates for the energy management system, checking high-voltage connectors.
Insurance is another often underestimated item. Electric and plug-in hybrid vehicles are sometimes classified in different rate categories by Belgian insurers, due to the replacement cost of the battery in the event of a claim.
A professional garage that handles both sales and maintenance can provide a realistic estimate of these recurring costs. Buying and maintaining in the same place simplifies tracking and allows the mechanic to know the complete history of the vehicle.
Test drive in Naninne: what a parking lot does not tell
A test drive in the garage parking lot rarely lasts more than five minutes and does not replicate any real usage conditions. The roads around Naninne offer a varied testing ground: 30 km/h zones in urban areas, climbs towards the Marlagne plateau, stretches of national road at higher speeds.
On a used vehicle, the test drive allows for the detection of defects that neither the Car-Pass nor the technical inspection mention. A noise from the wheels at a certain speed, asymmetric behavior during braking, a steering wheel that pulls slightly, an automatic transmission that hesitates between two gears uphill.
- Testing the vehicle cold, before the engine has had time to mask a difficult start or suspicious smoke from the exhaust
- Covering at least one mixed route (city, road, possibly highway) to engage all RPM ranges
- Checking the operation of all driving aids (adaptive cruise control, lane departure warning, rearview camera) which represent an increasing part of the vehicle’s value
A professional who accepts a long and varied test drive demonstrates confidence in the vehicle offered. Conversely, a seller who limits the test to a block should raise questions.
The choice of a car in Naninne is no longer just a matter of brand or mileage. The changing Walloon taxation, the technical specifics of electrified engines, and the variable transparency of the Car-Pass regarding battery status add parameters that only local professional guidance can help master as a whole.
