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.

Inspection checklist
BYD Sealion 7 I — inspection checklist
Things to check
- Demander l'état de santé de la batterie et la date de fin de la garantie constructeur.
- Faire contrôler par un concessionnaire BYD les campagnes de rappel éventuelles avec le numéro de série.
- Identifier la version : propulsion 313 ch (82,5 kWh) ou intégrale 530 ch (82,5 ou 91,3 kWh), la recharge rapide diffère.
- À l'essai, rechercher vibrations et craquements de planche de bord, signalés par quelques propriétaires.
- Contrôler le coffre avant (58 litres) et les accessoires de charge fournis.
Questions to ask the seller
- Quelle version est-ce (Comfort, Design AWD ou Excellence AWD) et quelle autonomie affiche-t-elle en charge complète ?
- Des vibrations ou bruits parasites ont-ils été traités sous garantie ?
- Pouvez-vous fournir le carnet d'entretien et la facture d'origine en France ?
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.
