A unique brand identity is a hugely important part of a successful product, whether that product is a specific trim of a car, a model as a whole, or an entire brand's lineup. Whether it's the Ford Mustang's three-bar taillights, BMW's Hofmeister kink, or Jeep's signature seven-slot grille, any automaker worth their salt has at least one recognizable design element.

Don't be shy, there are no wrong answers so long as you stick with automotive design traits.
