I'm pretty sure I would need some kind of camera to post pictures.

Maybe someday?
Rebuilding and detailing 1/18th scale die-cast is kind of a hybrid hobby.
Its the same skill set of normal model building, especially when you get to the point of scratch building parts, but its a much easier scale to work in and much more rugged in terms of durability and operating features. Most of the rules for building plastic kits still applies but you need to adapt them to working with the actual stuff they build real cars from.
The funny part about die-cast is they are
supposed to be complete when you buy them. The reality is that most of them (even the expensive ones) aren't.
