Mod Rod
From Jenny Everywhere Wiki
Jenny Cornelius called her car “the Mod Rod”. (PROSE: The Folly of Men, Birds and Snakes)
Laura Drake once mentioned that Jenny had previously driven a Mini, before getting her current Jaguar E-Type. (PROSE: How Jenny First Met...)
Behind the scenes
A line in Birds and Snakes which referred to the car as the “Mod Machine” instead of the “Mod Rod” was clarified on Discord by Scott Sanford as having been an unintentional slip-up, and he later corrected it.
