We have all seen many beautiful vettes (C1 thru C5). Some with in-the-open headlights, some hidden. This question can only be answered by our reaction to the new design. Not every car with hidden headlights has been beautiful. If the vette steps away from pop-ups today, whose to say it won't return some day. One of the concepts has a slit for headlights that looks to be no more than 1-2 inches wide at its widest. That look is almost hidden.
However, the treatment shown by Motor Trend and Road & Track looks hideous. Let's hope the designers / engineers.
