Ron, although we do have a group of world class builders here, the majority of us are in the beginner to intermediate range. And like you we are all here to improve our skills. Builders of all levels are encouraged to participate on this forum in any way. As for detail, you add as much as you are comfortable with, or just built it straight from the box. The important part is that you have a good time and do the best work that you can.
Christian, I'd planned to join in with a rebuild of my old roadster, but just realized it's based on the old Monogram kit. I'll have to see what I can dig up.
