The C6 SelectShift transmission may experience valve-body wear, while the rear axle can show bearing wear; knowing these common concerns can help you maintain your Marauder with value preservation in mind.

Comprehensive archival documentation, such as the Marti Report, is crucial to enhance the vehicle's authenticity and value in the collector market.
