All correct, noting that utilities could be fixed, variable or mixed. For auto manufacturing I'd guess mixed.

"Production costs" doesn't specify what it is. All direct material, direct labor and overhead are production costs. Overhead could be all sorts of stuff, including fixed. Leave it out.
Transportation? Are you meaning freight?
Power/Energy - that's utilities so ditto above comment.
Storage charges is in my opinion an incremental fixed cost. If you're trying to stay simple, I wouldn't go there.
You didn't specify that these had to be product costs. Can you think of some selling/admin that might be variable?
