Ray, a 4 banger would be great transportation for you. Unless this is a decently running car, I wouldn't even consider it. You have the tools and place to work on it perferably undercover. A garage is not a necessity but it makes things alot easier. I rebuilt the engine in my first car (67 Fastback 289 4 barrel, 4 speed)when I was your age. We did it in the driveway. At the time, my folks had a gravel drive way and no garage so it can be done. However, I had my dad right there guiding me which was a huge help. He didn't do much of the wrenching, just guided me and answered questions, etc. One of the grea-*test*-('") summers of my life. Keep working hard and save some money and you will get what you are looking for.
