I think more (and better) advertising would help with sales. These people are right, a lot of people that say they like the car, don't know what it is. They need to make some really neet comercials. Something showing that the wing is animated, and not fixed (one of the things that sets it apart). I think Chrysler had some good commercials for the jeep in the past. I loved the one where it was driving under the snow and came to a stop sign where you could only see the glow of the turn signal in the snow. That was a classic. There needs to be one that is memorable like that! Something to get people talking about it!
Good luck!
