Verdict

Buy with care

Grand SUV électrique de luxe de 5 125 mm, au coffre de 645 litres, disponible de 360 à 658 ch. Je n'ai pas trouvé de note Euro NCAP propre à ce modèle, et les retours publiés sur sa fiabilité sont rares : seul un rappel de boîte à fusibles sur des exemplaires fabriqués en 2023 est documenté, par une source unique. Faites vérifier ce rappel au numéro de châssis.

Market prices

Price unknown: not enough online listings for a reliable estimate. Compare several listings before negotiating.

Importing this model

Prices abroad

Yearly medians of each country's listings (AutoScout24, in euros; United Kingdom: cinch dealer, in pounds), over years with at least 3 listings. Useful to judge an import (add transport, inspection and registration).

CountryRangeMedianGap vs FranceListings
Germany€69,880 – €97,990 (2022 to 2025)€79,450—75
Belgium€78,995 – €83,712 (2023 to 2024)€79,945—9

Median gap shown only when the country's estimate covers the same years as the French one. Add transport, roadworthiness test and registration.

You are importing the car to:

Import penalty (malus) in France

  • The CO₂ malus follows the scale of the year the vehicle was first registered, in France or abroad (WLTP or NEDC scale depending on its registration certificate).
  • For an imported used car, it is reduced by a flat-rate discount based on its age in months (scheme in force since 1 March 2025). The weight malus also applies on first registration in France.
  • The malus is zero for a car more than fifteen years old or first registered before 1 January 2015.

Check an imported car's history

HistoVec only covers the vehicle's life in France. For a car coming from abroad, a VIN-based report helps spot inconsistent mileage or a reported accident.

Known faults

Manufacturer recalls

See the official list on RappelConso (new tab) (French government recall site: category “Automobiles et moyens de déplacement”, search “Mercedes-Benz EQS SUV”). A dealer for the brand can also check, using the vehicle identification number (VIN), that recalls have been carried out.

Recalls published in France (RappelConso)

  • 3 June 2025 — Un fusible peut être défectueux, ce qui peut entraîner une panne moteur ou une altération des fonctions de retenue et du tableau de bord. Cela augmente le risque d'accident, de blessures et d'incendie. Official notice

Inspection checklist

Things to check

  • Faire vérifier au numéro de châssis, chez un concessionnaire Mercedes, le rappel de la boîte à fusibles (exemplaires fabriqués en 2023).
  • Demander un diagnostic de l'état de santé de la batterie et l'historique de recharge.
  • Contrôler le fonctionnement de tous les écrans et des aides à la conduite pendant l'essai.
  • Vérifier la configuration : 5 ou 7 places selon la fiche Caroom.
  • Exiger le carnet d'entretien et les factures de révision en réseau.

Questions to ask the seller

  • Le rappel de la boîte à fusibles a-t-il été effectué ? Avez-vous l'attestation ?
  • Quelle est l'autonomie réelle constatée, et quelle part de recharges rapides ?
  • La voiture est-elle en configuration 5 ou 7 places, et quelle est la version exacte ?

Test-drive tip: read the fault codes

A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.
