everything ive known and been told was any AWD vehicle should be towed only by a flat bet. when i had my kia break down, and they showed up with a basic truck, i wouldnt let them touch the kia till they got a flat bed out there. no way i was gonna risk it.
sounds like the owner was too stupid too watch. i really dont blame the tow truck driver since the vast majority of 6's are fwd, and alot of people dont even know the speed exist.
