New here and to cars in general

Hello all, so I recently purchased a car that is going to change my life forever. Was recently in the market for a car. I had a 2000 Chevy Malibu that gave me no problem. So I considered a new car but after weighing the pros and cons I decided to go with an older car. I always loved the dart/nova/ Malibu look. I ended up getting a 1974 Dodge Dart swinger. Which bring me to why I joined. I'm not very mechanically inclined and neither is my dad. So I am here to learn. Any advice or links I can read into would be appreciated. I'm very intimidated with the whole process.
