Ok, so I always wanted a MB Diesel. I mean my entire life, it's THE car for me. So I just bought a 1975 240D Euro Spec with a 4spd 122k miles (very solid), since my soul-less Mazda *****box died. To make a long story short, I want to learn how to repair and maintain my car. Where should I start, besides listening to what the car is telling me and reading these posts? Is there any literature that is a must?
