I picked up the GoGo dealer brochure at Hill Kelly Dodge in Pensacola, Florida in 1965. (Wasn't old enough to drive, yet. Imagine that!) I still have the brochure. Anyway, I just thought "GoGo" was a slogan, not the actual name of a model. At any rate, Hill Kelly never actually had one that I saw, but they did have a yellow 65 Coronet 2dr hardtop with a black interior, Cragar mags with blackwall tires, and a 426 wedge/Torqueflite. I drooled over that one. . . .
When I first started showing my 63 Valiant convertible back in the mid 90s, some people asked me why I ran Cragars instead of rally wheels. My answer was (1) rally wheels didn't exist in 63, Cragar mags did (or at least pretty soon afterwards), and (2) Cragars were a factory option on 65 Darts, so Cragars were closer to being factory correct than rally wheels on an early A body. I didn't realize until later that the optional 65 Dart Cragars were 13 inch, because I had never actually seen one with the GoGo package, just the brochure. So mine were 14 inchers (now 15 inch).
