Hmmm, that's a tough one. To me "SHOW" has always been a flashy tough looking paint job with nothing under the hood, like say a 69' 6cyl sportsroof guised as a Mach 1 or Boss while "Go" has always implied a sleeper to me, like the multi colored primered cars we had in high school that had stealthy surprises under the hood waiting for challangers at the red lights. Admittedly my car has more show than go but with 300+RWHP it's certainly no slouch and can hold it's own if I ever put it to the test.
I guess I'd fall intot he "who cares" category most of all. When I lived in Texas Tang350 dragged me to a few show and shines (his nights and weekends were planned around these things god bless him) and honestly, I really did not enjoy it anywhere near as much as he did. I liked his company and all, but I hated all these folks telling me what wasn't right with my car, of which they themself had none. I bought my car for me and no one else. If they also get pleasure from it then good for them. I do love shows and will drive my car to them, but not enter them becasue I feel no need to compete. Besides it's far more fun for me to see people gather around a car out in the parking lot wondering and asking why it's not entered then to have them critique it on the otherside of the fence.
