Choosing a car and keeping it in good condition relies on measurable trade-offs: annual maintenance costs, frequency of interventions, and priority spending areas. Between a traditional combustion vehicle and a used electric one, the parameters to monitor are not the same, and budget discrepancies can be surprising.
Maintenance Costs: Combustion vs. Electric – The Key Differences
The comparison between a combustion vehicle and an electric model goes beyond the price at the pump or charging station. Maintenance operations differ radically, which alters the structure of the annual budget.
| Maintenance Item | Combustion Vehicle | Electric Vehicle |
|---|---|---|
| Engine Oil Change | Mandatory (annual or based on mileage) | Non-existent |
| Spark Plugs / Timing Belt | Periodic replacement | Absent from the powertrain |
| Brake Pads and Discs | Standard wear | Wear slowed by regenerative braking |
| Tires | Standard wear | Potentially accelerated wear (weight and torque) |
| Filters (air, oil, cabin) | Regular replacement | Cabin filter only |
The absence of oil changes, spark plugs, and timing belts significantly reduces mechanical interventions on an electric vehicle. According to L’Auto-Journal (September 2026), this simplification even poses a volume activity problem for some garages.
On the other hand, tires require increased vigilance on electric models. Their higher weight and immediate torque delivered to the wheels accelerate wear. A driver who checks their tires monthly on a combustion vehicle should adopt the same reflex, if not more frequently, on an electric vehicle.

Buying a Used Electric Car: Battery Check is Key
Sales of used electric cars surged in France in 2025. Their share remains small in the overall used market, but the trend is accelerating. This context makes pre-purchase checks all the more crucial.
For a used combustion vehicle, the instinct is to check the mileage, maintenance history, tire condition, and compliance with technical inspection. For an electric vehicle, the health of the battery takes precedence over the displayed mileage. A degraded battery can significantly reduce range, and its replacement is the most expensive item on the vehicle.
Specific Checks for Used Electric Vehicles
- The battery health certificate (SoH, State of Health): it indicates the residual capacity compared to new condition. A diagnosis from a professional equipped to do so can provide this information.
- Charging history: very frequent fast charges can accelerate cell degradation. The maintenance log or the vehicle’s onboard data sometimes provides information on this point.
- Manufacturer warranty on the battery: some manufacturers offer coverage for several years, transferable to the second owner. Checking its validity avoids unpleasant surprises.
The lower purchase price of a used electric vehicle does not guarantee an overall cost advantage if the battery is nearing the end of its life. Analyzing the SoH before signing is the most cost-effective step in the entire purchasing process.
Technical Inspection: A Schedule and Budget to Anticipate
The technical inspection follows a precise regulatory schedule. For a passenger car, the first inspection occurs in the six months preceding the vehicle’s fourth anniversary, after which the frequency changes to every two years.
Prices are freely set by each approved center. The discrepancies between centers for the same service justify comparing prices before making an appointment. Some centers offer reduced rates during the week or for online bookings.
Preparing for the Inspection to Limit Re-Inspections
A re-inspection prolongs the timeline and incurs additional costs. A few preliminary checks can reduce this risk:
- Check the condition and operation of all lights (low beams, turn signals, reverse lights, brake lights). A burnt-out bulb is one of the most common causes of re-inspection.
- Check tire wear. The minimum legal tread depth is set at 1.6 mm, but a tire close to this limit will be flagged.
- Ensure that the brake fluid, coolant, and windshield washer fluid are at the proper levels. A deficiency can lead to an observation or even a reason for re-inspection.
Routine Maintenance: Balancing Safety and Budget
The price of parts and labor varies depending on the chosen network (dealer, independent garage, auto center). For routine operations (oil change, brake pad replacement, filter changes), price differences between networks can exceed several tens of percent for equivalent services.
The manufacturer’s maintenance log specifies the recommended intervals for each operation. Adhering to this schedule protects the manufacturer’s warranty and maintains the vehicle’s resale value. Conversely, delaying an oil change or timing belt replacement exposes the vehicle to failures whose repair costs far exceed those of preventive maintenance.
Engine oil deserves particular attention on combustion vehicles. Using oil whose viscosity does not match the manufacturer’s recommendations can reduce engine longevity, even if the price per liter is lower. The oil’s compliance with manufacturer specifications determines the engine’s lifespan.
Regarding tires, pressure should be checked monthly. Under-inflated tires increase fuel consumption, extend braking distances, and wear unevenly. A reliable pressure gauge is inexpensive and pays for itself within a few months of use.
The choice between regular preventive maintenance and curative repairs after a breakdown is resolved by the numbers. A rigorous follow-up of the manufacturer’s schedule, combined with monthly visual checks (tires, fluid levels, lights), remains the least costly strategy over the vehicle’s ownership period.
