Yes they are 2010 plastics. It was a weird year or colors for the banshee plastics.....the blue color scheme had white rears and the red set had white fronts......it was sort of messed up.
Good luck with the sale, 4500 is a bit much though, its gonna be tough to get Banshee fanatics/experts to pay that kind of money....Just being honest. Maybe you will get someone locally to pay that or some young person who is looking for a banshee just like that. Good luck with the sale man.
