No one is going to mistake this...
for this...
And Acura is hardly the only auto-maker to have used a pentagonal-shaped grille - Mazda and Cadillac being among the others (the latest Mazda grille actually looking a bit like Hyundai's by being more hexagonal in shape).
Speaking of the hexagonal-grille shape, Hyundai was doing that before Audi and a whole bunch of other automakers who have been using that shape.
Uhh, fender vents have been used by numerous automakers.
Why not say an Aston or Alfa vent? Or a Buick or Pontiac vent? Or a Land Rover or BMW vent?
Also, it's not like Lincoln came up w/ the thin, horizontal taillight element.
Hyundai used it on the iFlow concept in 2010, several years before the MKZ went into production.
Furthermore, the taillights of the Conti are very similar in shape to that of the Azera.
Gee, that must mean Lincoln
copied Hyundai and not Bentley!
Speaking of which, only 2 times has an automaker been called out another publicly by another for copying - Mercedes (calling out Toyota/Lexus for the LS430) and Bentley (calling out Lincoln for the Conti).
Both Bentley designers at the time (Donckerwolke and Lee) are now working at Genesis/Hyundai.
