I checked out the iM in-person today while waiting on regular service maintenance on my 2015 Toyota Yaris SE. The dealership had over a dozen iM's on the lot (mostly silver & white), and the one Barcelona (Dark) Red Metallic they had onsite really put the other colors to shame. Pictures do NOT do this color justice at all. It is absolutely gorgeous in-person, and really pops with all that black trim work. Plus, the iM taillights blend perfectly with it. I can't believe this is the least-popular & rarest color for the iM. I'm not usually a 'red car guy', but this is easily my top choice if I decide to pick up a 2018 iM in the latter half of 2018. 2nd choice would be Blizzard Pearl White, since no Dark Gray or Falcon Gray Metallic color is available on the iM.
