B and C are specific as to the car mentioned. H is a bit more general, though the car pictured is specific to the use of a car, as mentioned in the song it is linked to.
To clarify, some of the songs do not have cars as their central theme, or their titles. In some cases, the use of a car is part of the song, though no brand or model is mentioned, as with car pictured in H, and with the previously identified "Hitchin' a Ride"
A thumb goes up, a car goes by
Oh, won't somebody stop and help a guy?
Hitchin' a ride, hitchin' a ride
Been away too long from my baby's side
Ride, ride, ride, hitchin' a ride
Ride, ride, ride, hitchin' a ride
