1973 Volkswagen 412

1973 Volkswagen 412. It was running when it was parked for the last time and that’s been many years ago. I couldn’t get the hatch up to show the motor, if you have any pointers on this please share what you know as I’m clueless, I tried pushing the button in and got nowhere. Feel free to ask questions and I’ll do my best to answer them. The odometer reads 02365? Sales “as is condition”.
