Besides Revell supposedly coming out with a composite model of the 914, AutoArt has several colors of the 914/6 WITH FLARES set for release in 2010!!!
CLICK HERE for website where I found info.
Or GO TO THIS PAGE to see list of colors (scroll down a bit or search 914)
Green, orange, red, gemini blue metallic, saturn yellow, and orange.
Of course, AutoArt models aren't cheap but they sure are nice.
