Selling car / money by bank transfer

My parents are currently selling their small car, which still has a 3 year warranty. https://suchen.mobile.de/…/details.html?… A single interested person has called up to now. Instead of calling, he wrote by email. First they asked if the car (after one day) was still there. Then they asked what our best price for the car would be. Since I thought it was nothing, I simply gave him the sum, without big text around it. Now this answer came: – Thank you, that you I am satisfied, but can you assure me that I will not be disappointed when I buy this vehicle. I am willing to pay your price, but not personally, because I am in a mission conference right now and my fastest payment option is bank transfer, which is safe and fast and I will pay for the bank transaction fees so that you can get the expected amount. I hope we can purchase As soon as possible? Since I buy the vehicle for my son and I am very sure that he will love this vehicle, he is a mechanic and a practical man, so if there is something that needs to be repaired in it, just let me know that he will handle it. I have a forwarder who will come to pick up as soon as the payment is made on your account and he will take over the title for me. Bank name: Name of the account holder: Accountnu mmer: BIC: IBAN: Total amount in Euro: Address for the collection: Once I have received the data, I will continue with the payment via my bank and confirm to you as soon as the payment is completed as possible…… I wish you a nice day. Thank you – The car still has factory warranty. Doesn’t he understand that? Or is there a risk of fraud? I am aware that you can’t bring back transfers, that only applies to direct debits. But I would have didn’t think he wanted to buy the small car with such a show. Am I too distrustful of the action? Courageous of him to just transfer almost 7,500€ somewhere, didn’t I?
