Questions about example sentences with, and the definition and usage of "Jitney"

A: It seems that it came from Chuck Berry’s “You Never Can Tell” song composed quite some time ago. It seems that he is talking about a jitney(A bus or other vehicle carrying passengers for a low fare ;Oxford Dictionary) that has been souped up( probably a modified version) and was a cherry red ‘53 series. In conclusion, I believe that this sentence is talking about a modified bus with a cherry red paint job that was launched in ‘53 (1953). I hope this helps :D
