You are importing the car to:

Import penalty (malus) in France

  • Emissions of the versions in this guide: 0 g CO₂/km (check the value on the car's registration certificate).
  • 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.

Inspection checklist

Things to check

  • Contrôler le fonctionnement du toit de ce cabriolet, ouvert et fermé, et rechercher les infiltrations.
  • Tester l'électronique : écrans, connexion du téléphone, déconnexions, messages d'erreur.
  • Vérifier la recharge sur borne AC (11 kW) et sur borne rapide DC (144 kW annoncés par Fiches-auto).
  • Contrôler la finition (jeux, bruits parasites) et l'état des jantes et des pneus.
  • Se renseigner sur la garantie restante et l'atelier MG agréé le plus proche.

Questions to ask the seller

  • Y a-t-il eu des pannes d'électronique ou des déconnexions, et des interventions sous garantie ?
  • Quelle version (340 ch propulsion ou 510 ch) et quelles options sont montées ?
  • Quelle est l'autonomie réelle constatée, toit ouvert et fermé ?

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.
