What, no doubt, bring water to the mill of opponents to forced walking to electrification at all costs of the new fleet. Better, they believe, push the ancestors towards the exit in favor of new thermal vehicles more affordable in terms of price, which would have a very positive impact on CO2 emissions.
During the first six months of 2025, the average age of used cars registered therefore increased up to 9 years and 9 months, against 9 years and 6 months previously.
Diesel decline
Without too much surprise, petrol cars are the most popular on the second -hand market, with 55.8 % of transactions on their own, upgrading diesel.
Even if the implementation of the new phase of the bass emission zone in Brussels was postponed to January 1, 2027, Brussels residents and commuters to the capital have little reason to buy a diesel vehicle, whether new or used. The prohibition of circulation of diesel vehicles on January 1, 2030 remains in effect in the capital. What logically weigh on sales of new diesel cars, which represent only 3.8 % of the total against 5.7 % in the first half of 2024.
With or without battery, your electric car?
On the second -hand market, the fall is also marked: 27.4 % of the volume in 2025, against 32.1 for the same period last year. “”Diesel cars remain loss of speed, mainly for the benefit of rechargeable hybrids “.
Unlike new (where they represent a third of registrations thanks to the craze of fleets for this most interesting fiscal engine), electric cars always have a senator look on the second -hand market, which of course needed to be fed by the arrival of a quantitative offer. “Electric cars are gradually gaining ground on the second -hand market and today constitute 3.9 % of the total, mainly thanks to the rise in leasing cars”, note Filip Rylant.
Golf, Polo and Corso ET RO GOLOVANT: LE Threesome GOLO
However, this is not (yet) the craze. “There is a Increase marked by the demand of electric cars thanks to an increasing offer and the drop in prices, but purchases remain limited, in particular due to the limited knowledge of consumers and the uncertainty weighing on the batteries “, Note Matthias Gommeren, CEO of Cardoen. “LSUV, of all sizes, retain their popularity rating. But individuals remain little asking for electric cars. It is in companies that demand for both electric vehicles and PHEV (rechargeable electric hybrid) is the highest “, observe Wim Bruggeman, at the head of the activities of the Dex company.
“Rechargeable hybrid cars is the worst of the two worlds”
It should be remembered, the second-hand market is mainly the case of individuals: 90.5 % of registrations are carried out by private persons. “”Used car brands that dominated the first 6 months of 2025 are Volkswagen and BMW. The top 5 is completed by Mercedes, ahead of Peugeot and Opel “, Who had his 4th place checked for the benefit of the lion brand, specifies Traxio in its press release. “”Among the most popular models in the cumulation of the first 6 months 2025, nothing has changed for the top 5. Thus the VW Golf (14,706 registrations) still comes first, in front of the VW Polo (10,608), the Opel Corsa (9,287), the BMW 3 Series (8,386), and the BMW 1 Series (7,750) “.
