Mercedes G63 AMG 6×6 vs G63 AMG (video)

Mercedes G63 AMG 6×6 vs G63 AMG The Mercedes G 63 AMG is a mad car in its own right (although not as mad as the G 65) and costs almost £125k before you start ticking any option boxes.

Mad and irrational though the G 63 may be, it now has an even madder sibling – the Mercedes G 63 AMG 6×6 – which not only adds an extra axle for 6WD but comes at a price – almost £400k – that makes the G 63 seem a bargain.
