OWNERSHIP & BUILD FOCUS
What matters now
Two-year window
The short 2006–2007 run makes the final Monte Carlo easy to define and increasingly distinctive as clean examples disappear.
LS4 changes the character
The SS is not simply an appearance package: its V8 torque and associated chassis hardware give the final Monte a different identity from the V6 cars.
Coupe-specific condition
Door/hinge wear, body trim, interior plastics and hard-to-find cosmetic pieces deserve extra attention because the coupe has fewer surviving donor cars than Impala.

REFERENCE STANDARD
Master Customs prioritizes factory-era documentation and period road tests, then uses established enthusiast references for service and ownership context. Equipment changed by model year and RPO; verify a specific car by VIN/RPO and factory service information before ordering parts.
