Vintage Air wafts, bumpin’ audio
wall makes you forget about texting
and the urge to share your good
spirit with mean-spirited yahoos, and
think you’re somewhere else. Sink
into premium seats; between them
the custom YearOne center console. A
nice place to pass the miles because
the Chevelle gobbles them up like it
was in a hot dog eating contest.
That’s the time when John G fondly
reminisces the six years it took get
here by his wits, Mary Ann’s pioneer
mentality, and where he would be
were it not for his father’s devotion
to him and to the sport. John G’s
most appreciative of the Chevelle’s
performance and the quality of its
ride, something he feels every time he
is going to a show or crankin’ out on a
cruise night. That’s the very best part
about all of this. CHP
