[Number 3]

Generally well over a year from the first prototypes with JC Witney headlamps. Go back and check the first C7 sighting and the actual on sale date.

If GM were to unveil at the NAIAS next January then there should be spy photos now.

To do a fall of 15 launch, normal 2016 MY timing would have CTF cars in less than a year. CTFs are generally 3 months or so ahead of the ship to customer date.

Very possible they are doing something very secrative but we should be seeing something very soon for a January 2016 launch.

And you can continue to sell a 2015 model right up to the end of that calendar year if I recall the rules for certification correctly.

With no prototypes in Camo yet photographed I don't see how we get a car on sale in 13 or 14 months.
