just got car back from Eurocharged due to vibration issues at around 70MPH, so decided to take the faster, longer route home from Harrow; M40. well the new engine mount has worked and vibration gone. Decided to fluctuate speed from around 70 MPH to XXX MPH; being 7.30 am roads were still quiet. saw a nice jaguar XJR and he pulled over politely from 4th lane to 3rd, new shape Range Rover sport in front decided he would push speed up; he was already doing 90 MPH, I politely kept my distance but he was reluctant to pull in the 3rd lane to let me through and just kept increasing his speed.... eventually he pulled in the 3rd lane and I passed by around XXX MPH, was waiting for him to come up behind me but gather realised the vehicle I had, and he reduced to 80 MPH. I obviously had a big grin on my face. as with most AMG's; when someone sees the car in their rear mirror it can look standard but when it passes and you see the various mods, quad exhausts etc. they assume its a 'fast' one but in one way I do like the look of the car but I am getting twitch to strip all the 'go faster' markings of it and to make it look more discreet and sense of satisfaction may increase?
