When I was about 12 years old, the local newspaper had a running comic strip of a some time detective character name Mike Nomad (a partner with Steve Roper) who was always in some thrilling action. What I recall most about the strip, was Mike drove a 64 Dodge Dart (may have been a convertible), and also rode a Vincent Black Shadow. Don't recall that the strip ever described his bike as a Vincent, but even at 12 yrs old I knew it was a Vincent. I think his Dodge Dart was also built up like some sort of street-strip car. I recall too that many of the depictions of vehicles in traffic showed Mopar cars and trucks.
