要交钱的,不必买卖双方到,你到就行。除了registration fee外,你是从dealer处买的吧。那你付钱时,应该只交了7%的税,另外7.5%的税,要交给SAAQ。所以最好带你的支票去。
另外你还要带齐文件。就在我上面给的那个link里,点开Registering a vehicle purchased from an automotive dealer,内容如下,按上面写的带齐。
Registering a Vehicle Purchased from an Automotive Dealer
If you are buying a vehicle from an automotive dealer, go to a SAAQ service outlet with proof of identification, preferably your driver’s licence, and an "Attestation de transaction avec un commerçant" form duly completed by the automotive dealer.
If you do not have a driver’s licence, contact the SAAQ to find out which documents are required.
If you are buying a new vehicle, you must have on hand a form entitled “Description of a new vehicle”.
If you are buying a used vehicle, you must have the prior registration certificate, bearing the signature of the former owner and the automotive dealer.
