Could somebody with some design experience help me pinpoint exactly what it is about this clay model I spotted at Hershey that makes me question the owner’s assertion that it emerged from the GM Design studios in the 1950s? There’s something just too modern about the way its curves interact with its knife-edge lines, something too jarring about the juxtaposition of the Motorama-like trunk strakes and portholes against the 1990s flush bumpers. Then again, maybe this really is some GM designer’s vision of Buick sports car that never was.
