I finally completed the transaction last weekend and was able to drive her home. Got to love French bureaucracy, over 4 months to update the registration on the car so it could be transferred to me.
I am looking forward to getting it back to Melbourne later in the year. Until then will have fun driving around Paris.
I would upload a pic but the size restrictions of site make it impossible. Note to site admin, you need to look at this. Site needs to be brought up to date, it barely works on mobile and has limitations that would have been relevant 10 years ago but now cause issues.
