I've only an M sport but if I'm in the outside lane on occasion I'll get the 18 year old in his Civic, when I'm in the M5 though everytime I'll get everyone try to have a go but the beast'll just chew 'em up and spit them out
My best was a 911 Turbo 996, guy about 24 thought he was a Baller and then I just left him, guys face was priceless when he caught up
'M' cars in the UK at least are looked highly upon and if you're in the outside lane loads of people will have a go at racing with you, until the 5-0 turn up
must admit if I saw and X5M I'd race him
