At an emotional crossroad
Let me start by first saying your story is very heartfelt and one of the more touching stories I've ever read on this website. Maybe it's just cuz I can also relate to a lot of it I met my dad when I was 27 with a boatload of animosity, he moved away from my sister and I and mother when we were about four started a new life halfway across the United States putting my half siblings through college while my sister myself and Mom struggled on welfare. I also learned what not to do as a father from him. I feel you should build your car as others have said within your means get it up and running and begin to enjoy it. And as time goes by you can move to that dream hemi if opportunity presents itself. The best of luck to you.
