£4k of options on an E Class Coupe? Given that you will likely sell it after 4 months what's the point? I can understand COMAND and maybe metallic ( but white is good and free), but other than that what options do you want/need?
The spec isn't too bad anyway, and the artico trim is as good as leather.
You're welcome to take over the lease on my 640d if you want to (£470/month). I don't use it anymore as am about to go back to sea for 3 months and then start a new job in London in the summer and will be using the train.
