Hey Japanese dude - quit ripping off my stuff!
Rest assured, my advice is from my own personal experience - no books etc.. Your list is a good one - very close to my own. Cars rarely make the deal, but they can break the deal. You don't want to show up in a Trans Am or the like. I can't speak on the effects of "The Godfather". The coloring book idea sounds like a deal breaker to me. I could be wrong, but I would think it would send out a "gay" vibe or at least indicate mild mental retardation.
