I saw that before this online malarky sums <€15k didn’t have to be reported - seemed pretty generous - but now, being digital, all must be reported.
However, the €15k threshold of old may indicate a level of exemption still extant.
I understand it to be that … One has to declare all, explain.. and wait to see how it turns out…
Seems any sum which is out of the ordinary to the donor/recipient… will/might draw the attention of them in charge, due to so much money laundering going on. Most of us are innocent of such, but we are not exempt from “telling-all”.
the French Tax Bods will decide what tax if any is due.. .. 
No. Notarising the document wouldn’t change the facts that this transaction was not intended to be a gift. Notarising would add nothing (bar costs!). As above, better to accumulate as much evidence as possible of the intentions and actions taken. It’s a pity about the CG costing so much to amend, as this would have been powerful evidence of joint ownership. Make sure there is a good audit trail to support the € reasons why you’re not proceeding with amending the CG. Ensure that both names if possible are on any other documents associated with the car - eg insurance policy (if at all possible), servicing/maintenance invoices etc etc…
