Car sales to Spain – is this man serious?

Hello everyone, I have advertised my car on Mobile which is why a Spaniard wrote me on Whatsapp, he is interested in the car. At first I was very skeptical but then wrote a little bit with him back and forth. He meant the car is comparatively cheap and he probably wants to resell it in Africa. I know these scams with collection by third parties, alleged transfers via strange banks with deposits etc. But he doesn’t want to. I come from Wie n and he said recently he was still here himself. He wants to come here personally to pick up the car and pay cash. He also sent me photos of his cash, because I was skeptical because of course I can’t distinguish between real and false money. (That was very strange I have to confess). He asked me to have the money checked here in Vienna before by a bank or to deposit and then to do the paperwork. One thing you have to keep him good he is not very “pushy” . Don’t write to me all the time and when I first got rid of him, he took that and didn’t want to convince me of himself the whole time. I am a little in discord but if he really comes to me personally, gives me real cash confirmed by the bank and I give him then the car can’t go wrong after all? At least I don’t recognize any fraud so far. Look forward to your feedback or any tips I should pay attention to. te!
