Certainly, the most complicated business for us was getting the European certificate of conformity (the Skoda was very funny - Skoda France saying get it from the UK and Skoda UK vice-versa - we eventually prised it out of the British end. With the Landy, it came from Landrover France - go figure.) The problem with British registered cars in the France is that if they are not exported, UK insurance companies will often wriggle out of their obligations to settle a claim (not a worry if you don't actually live here, but a total no-no if you pretend you live in the UK but don't actually do so.) With any average car, the process of importation is pretty simple, but the cost varies according to CV ratings so the less powerful it is, the cheaper it gets.
