Looks like you are doing great. I love doing construction work it moves on so fast. The finish work is what drags out, lol. My parents signed for me a work permit at 14 and I worked in home construction for 5 years while in high school and tech school. So that helped a lot when I built my garage. I also flipped homes for my daughter and son. If you do your own work it never ends there is always another project that needs done.
You will get to enjoy the garage soon get the COO and move the cars in.
Great job,
David
