There is no way on earth that a car of this calibre should behave in this way but to be honest I'm just not up to the battle at the moment. I'm not very well and as previously mentioned I've just given up a 20+ year 20+ a day habit. Cold turkey is a bitch and I feel like shit.
I will come back to this though. Luckily the service manager drives one of these and I've got to know him rather well over the last few months. I'll probably drop him a line and ask him to take my car home one night.
