Not EQG.

So, it’s the main six’s sweet 16, and they get to by whatever car they want. Question, what kind of car would each of them drive?

Twilight and Applejack would likely buy a car that's cheap, piratical, and utilitarian.

Rainbow Dash might be an idiot, and buy a so-called "sports car", when the less expensive cars are just as good.

AJ - a mid-90s beat-up Ford or Dodge pickup
Twiggles - any electric car
Dash - Mustang or Camaro
Flutters - a VW beetle
Pinkie - VW Bus modded for instant parties
Rarity - Caddy, Benz or Beemer
