Good morning, I have recently found a w115 Mercedes-Benz 220D that used to belong to my grandfather, unfortunately when he died the car got stored in a garage and my whole family forgot about it. I am very inexperienced but I was thinking about fixing it since it doesn’t seem in bad shape. Have you got any suggestions on what I have to do? Keep in mind that I don’t know anything about anything so don’t be afraid to state the obvious. Thank you very much
