Not sure if same applies to USA but suspect parts different..........off another forum.....
If you bring a uk car to france, you will need to follow the following steps:
1. Get a certificate of Conformity for the car, usually from the manufacturer and occasionally for a small cost. Other documents you will need are proof of habitation in france (bill etc), the ownership docs from the uk.
2. Have a garage replace the headlkights in the car, so they are ok for france....doesn't apply in france I assume!
3. Have a controle technique (french MOT) done on the car to verify fully it is in working order.
.Take the documents to your local tax office to get the form showing either their is no import tax to pay, or that you have paid it. If you have a receipt showing your purchase of the vehicle, so much the better
5. Now, either go to your local Mairie, or for a quicker resolution, the local
prefecture and there you will need all of the above gathered documents plus passport, with all of this they will issue you with a form, which you take to the payment office (around 400 euros to pay) and then you will be issued with a carte grise (ownership doc in france.4
6. finally You will use the carte grise to get new reg plates for your car; you will also need to inform your now French insurers of the change in number plate.
