Honestly? If you’re going with heritage/stereotypes?
Mustang = White trash that didn’t have enough money for a Corvette.
Hyundai used to = Someone cheap who didn’t care anything about the appliance they drove.
Hyundai now = Someone who gets good value for money.
FYI, I drive Jaguars. You don’t get too much more “out of the mainstream” than that.
I remember hearing about how Jaguar was going to target the affluent gay community. Someone suggested their slogan be: "Be the f*g you are in a Jaguar."
