Parking at a metro station in south west Paris

[Suandpete]

Hi

We will need to travel from north Deux-Sevres up to central Paris to go to the Chinese embassy to get visas.  I realise that we can easily get a TGV from Poitiers but we are also considering driving up and leaving the car near a metro station in the south west of Paris - can anyone suggest a station with nearby parking?

Thanks in advance
