Add chrome strips to the tail gate, and build it. It is the perfect Chevrolet for a lot of Americans, from Boomers who want a chance to own a new, efficient Nomad, to those needing either a small sports car with storage or a second vehicle to park by My gorgeous 57' Nomad andTahoe. Frankly, I'd pick it over the Camaro (I have had 4 Camaros, from A 67 to three new ones 71' Z, 78' Z and 96 SS) because of its size and versatility. And I do think more versions off the same platform is a good idea, even 2 roadsters. But they have to be different enough (the Solstice and Sky, I think, are different enough.) Add the Nomad, a Solstice hatchback - and maybe another model, and the line will keep running.

I may need A new Camaro to?
