Jannik,
You'll soon realize that working on your car will be a joy, even when things are all going the wrong way. Keep the dream alive and realize that doing just one little thing will be helping you reach your goal. You're actually well ahead of where you think you are. The car arrived already separated from the frame. This will make it much easier for you to build it the way you want, the right way. Mine came all together, and I often wish, usually with my arm stuck inside some hard and cold place, I had done a body-off restoration.
