After financing request still possible to act?

Good day to the forum, my question: I have to buy a Golf 7. 5,000 euros can I pay directly and the rest (in total the golf costs so far 18.500) I want to finance. I bought a Q3 last year and paid in cash (25,000 euros, I understandably did not have this option anymore) since the seller said he would have had more room for negotiation if we have financed. Now we want to finance and there is (which is a miracle) suddenly wi The data that go to the bank are also consistently positive I have an indefinite AV and my husband (guarantee) is a civil servant during his lifetime. Also and that’s what the bank is all about after deduction of all fixed costs (rent, insurance) is still 3,000 euros net available for free. If the financing at the bank is “through” you can get bad and say: okey the contracts are now signed on the table is still going on. he me? salutary elisa
