Buying a car in 2026: what to weigh in for the years ahead

By Vincent Clarenc, Founder of Compar'Car

Buying a car used to come down to comparing a sticker price, a monthly payment and a few options. In 2026, that reading grid no longer holds: regulation is moving faster than a vehicle's lifespan, financing is changing in nature, and the political and economic climate stays uncertain from one year to the next. Here is what actually matters for a purchase meant to last several years, not just a few months.

Regulation is not going to loosen up

A car bought today will have to deal with stricter rules than the ones in force at purchase, not looser ones. The ecological and weight penalties have tightened sharply since 1 January 2026 (threshold at 108 g CO2/km, weight penalty from 1,500 kg), to the point of now affecting around 72% of new cars sold. Low-emission zones follow the same path, with a timeline that varies by city, even though 2026 saw some regulatory back-and-forth on the topic (votes to scrap them, then reinstatement by the Constitutional Council). At the European level, the 2035 deadline for the end of new petrol sales keeps shaping the market's supply, even if it remains subject to adjustment. Worth noting: a low-emission zone doesn't block resale, which remains possible anywhere in France through national platforms such as LeBonCoin or La Centrale — the constraint is local and time-bound, not a hard stop on the vehicle's value.

The cost is no longer just the advertised monthly payment

Financing itself is changing in nature. Leasing — LOA and LLD combined — already accounts for 63% of new car registrations in France, and LOA moves under the consumer credit framework on 20 November 2026: mandatory APR, a right to early buyout, a withdrawal period. This shift makes it essential to compare total cost over the term — instalment or depreciation, insurance, maintenance — rather than the monthly payment alone, whichever financing method you choose (LOA, LLD, loan or cash).

Energy costs weigh more than the purchase price

Over a vehicle's holding period, energy often matters more than depreciation. The gap between fuel prices and electricity (or LPG) has already widened in recent years, and it weighs all the more on longer, regular commutes. A higher purchase price can therefore be justified by a lower running cost over five or ten years — and conversely, a cheap model can turn out to be expensive every month if the powertrain doesn't match actual use. It's a calculation to make over the planned holding period, not just at the moment of signing.

A political and economic climate that stays unsettled

The regulatory framework moved a great deal in 2026 — the penalty scale, low-emission zones voted out then reinstated, the LOA reform — and nothing suggests that instability is over: every finance law can redraw the thresholds. The market itself remains flat in 2026, with a more dynamic recovery expected from 2027 according to AAA Data, against a backdrop of modest economic growth and squeezed purchasing power. The average price of a new vehicle reached around 36,300 euros over the first five months of 2026, while the average used-car price dropped back below 20,000 euros in 2025, the first time in three years. This shifting climate encourages comparing more broadly, new and used mixed, rather than betting on a single category or a single regulatory scenario.

Mobility habits are changing too

Owning a car is no longer the only default: car-sharing, peer-to-peer rental, the spread of remote work cutting into some commutes, expanding public transport in large cities — these alternatives change the question being asked. Before choosing which car to buy, it's worth asking whether one car, two vehicles in the household, or a shared arrangement actually fits your real trips in the years ahead.

How long do you plan to keep it?

The average vehicle holding period in France is about 6.4 years in 2024, up from 5.5 years in 2019 — but that figure hides two different realities: a short 3-to-4-year cycle for most LOA or LLD leased vehicles, and a longer cycle for vehicles bought with cash or a loan. The French vehicle fleet is also ageing (over 11 years old on average), and roughly a quarter to a third of drivers are considering changing vehicles within the next three years. Asking this question before buying, not after, often changes which powertrain-and-financing combination actually makes sense.

How Compar'Car helps you decide

These criteria don't work one at a time, hoping it sorts itself out afterwards: a good powertrain poorly financed, or energy costs poorly anticipated, are still poor choices. That is precisely why Compar'Car's profile brings your budget, financing method (LOA, LLD, loan or cash), trips, mileage and charging options together to score every vehicle in your selection — new and used mixed — against your actual situation, rather than one spreadsheet tab per criterion. The regulatory and political climate will keep moving: that's what our dedicated articles are for, tracking it for you, alongside the profile.
