Mercedes-Benz’s GL450 is a full-size three-row SUV that was based on the M-Class platform. The GL450 took home several awards from Motor Trend, Car & Driver and AutoPacific, as was available with V8 or diesel engine, and featured Benz’s 4Matic system before it was discontinued. Your GL450 might have been equipped at the factory with Pirelli Scorpion Zero, Continental 4x4 Contact or Bridgestone Dueler H/L 400 tires as OEM.
