A moe toolbox will go well with your ita-sha, and as for a moe CV book, perhaps only necessary if you wanted a job at a maid cafe.
I’ve never seen a manga-adorned car myself, although there is no shortage of be-spoilered and be-skirted mini-vans farting around town with their after-market exhausts which certainly qualify as ita-sha in terms of my own eyes and ears.
Unlikely, but it would great to see an Index or Kannagi ita-sha soon:)
