Verify full supercharger service history including documented supercharger oil changes, treat absence as a red flag
Request a scan tool readout for all live and stored fault codes, especially boost and fuel system related codes
Inspect supercharger belt, tensioner, and bypass actuator for wear, cracking, or sluggish operation
Check brake rotors for deep pitting beyond surface rust, this is common on stored or low-mileage examples
Confirm the car has not been modified with an aggressive aftermarket pulley without a proper supporting fuel system tune
Test fuel delivery under hard acceleration to confirm no fuel pressure drop or hesitation at wide open throttle
On ZR1 cars, confirm the dry sump oil tank level and check for any history of oil scavenge pump issues, since this system differs from the wet sump CTS-V and ZL1

All three applications share the same core LSA block, supercharger, and known wear points, so buying advice is the same regardless of which car it came in. The one meaningful mechanical difference is the ZR1's dry sump system versus the wet sump used in the CTS-V and ZL1, which matters mainly for owners who track the car hard. Do not chase the ZL1's slightly higher factory hp figure as a reliability signal, the extra power comes from intake and tuning changes, not a stronger internal component set.
