The Dax side has the "white/lady" Dax, we have the black `78 model CT70. Both are destined to become iconic versions of their respective models. You just cannot go wrong with basic black, on a classic collectible vehicle. White, red & silver all kinda vie for second place on the color list. Those are the only color choices that stand outside of fashion trends/fads...and only one is actually a color. The rest are monochromatic choices.
Both of the feebay bikes shown are screaming deals. Replacing/redoing all of the chrome, unobtainium and one-year-only details, from scratch can easily top $2K. That's without touching anything else, like the motor, body/paint, exhaust, wheel assemblies, etc. K3-`78 models can be the most expensive to restore. A pristine, sub-500 mile original, should be worth ~$4500, with title. The market hasn't yet caught-up with 2015 economic reality and lack of paper is gonna hurt. Can you say "investment potential"?
