Hi Xavier, greetings from Czech Republic. Do you still have the wagon without the title? If nothing has changed in our legislation lately, we could get the title for historical vehicle just with the purchase contract. Maybe you might be able to get your plates when imported back to France based on the historical title? Just idea to consider. How about other countries maybe closer to you, like Belgium or Germany, did you check the procedure and then re import?
My country have age limit for vehicles made outside EU / without EU certification (popular are muscle cars, pickups or big SUV) and needs to be 8 years old or younger, in order to be eligible for registration and obtaining title. No EU certification require to pass few technical tests which could reach costs up to 2,000 USD. Anything older, can not be registered unless have a title from EU. To pass this obstacle, its not uncommon to get the German registration first, where is no this age restriction. Then you can proceed as standard import being under age of 8 years. Long story short, just the missing title should not stop you driving your car and hopefully you might find some way around the legislation.
For the historical title, the car must be in very good shape, no rust and mechanically sound, nice interior. Lately is accepted "california sun" patina until certain level and mainly minimum age 30 years. In France, you do not have anything like historical vehicle title?
The condition for historical vehicles in my country are very good, cheap insurance (usually 1/12th of the standard rate - 20 USD per year in my case), renewal check for condition every 2 years (40 USD) and must be member of some historical club (100 USD). Actually I passed today the TUV inspection for the brake check and goes for renewal check on Friday - this time because of covid, it will be kind of drive inn to keep the social distance.
