Car design is pretty conservative and derivative. Sometimes, however, car styling crosses the line from 'referential' into 'total ripofff' territory.
It's no surprise that new cars often look like some older models, or that cheaper cars often emulate more expensive exotics. Why? Well, there's only so much design room to play with. All cars have their headlights, wheels, taillights and grills in pretty much the same places.
Beyond that, car buyers are fairly conservative. Breaking totally new ground is seriously risky business and just about nobody tries it.
And sometimes new car makers think they can cash in on more prestigious looks from other makers. Just take a look at an original Toyota Celica fastback and compare it to a bigger, earlier Ford Fairlane 500. It's like Toyota just shrunk the Ford in the wash.
