to be honest i didn't read entore article either i just looked at the lap times and surprised to see the x5M quicker than the e60 m5
I'm a member of another m5 forum bc my prior cars were m5.. and I mentioned somehting about x5M being quick and great and this guy jumped all over me - like it was a personl insult to him! lol
my only point was X5M are great cars.. and a great option if the m5 is not able to meet your needs for some reason..
i love my x5M
