Buyer's Guide
What to look for
Chassis and engine authentication
Authenticate stamped chassis and engine numbers against factory or club records. For the G 63 6×6 specifically, verify chassis identity and delivery-market documentation against Mercedes-Benz records, confirm the six-wheel-drive hardware, portal axles and on-board tyre-pressure control are original and functional, and check condition of the M157 twin-turbo V8 and 7-speed automatic on any car offered.
Body and originality
Confirm body originality, panel identity and restoration standard against a marque specialist.
Mechanical inspection and service history
Confirm continuous service history and any rebuild history for the engine, transmission and driveline against a marque specialist.
Provenance and ownership history
Restoration standard, originality of body and driveline, and any documented ownership record are the main value drivers.
