I wish mine was that messy. lol Mine was way worse than that 9 years ago and I moved in at 9 1/2 years ago. I now have a trail to walk only on 1 wall the other 2 walls I would have to climb over stuff and cars.
I don't think a messy garage is a bad deal mostly after seeing the picture of your Hot rod gonna be that you posted a long time ago. I still remember it and would be a sweet build and would love to help on that one.
cars and parts is not messy and if ya could post a picture of that old A or T again I'd love to see it.
