The long version

GM built the C6 Z06 around a target weight more than a target price, stripping sound deadening and fitting a magnesium engine cradle to keep the 7.0-liter LS7 as light as the spec sheet demanded, a package that reads like a track car with license plates. That focus came with a real cost: the dry-sump oiling system was famously unforgiving of sustained high-g cornering, and a generation of owners learned to respect the oil temperature gauge the hard way. Values slid through the used-car glut of the 2010s, then started firming again as buyers rediscovered how rare an unassisted, naturally aspirated manual coupe like this has become.
