The one reviewer is a coward... Quoted "Althought the M5 is a lot of fun in, lets say a Parking lot, where you can spin it around and smoke the tyres and have a lot of fun, I just prefer the AMG because when I'm going through a canyon run, I want to be able to know I can go around corners safely and get home without damaging the car or myself."
Thats not a driver nor a car enthusiast. IF he wants to get home safe, go buy a small slow car... Idiot.
I think the M5 just scared the shit out of him.
