Thanks.
I am currently trying to track down all the detail about the car. So far I'm very impressed with BMW. I went to Coopers today and they gave me a full printout of everything that has been done to the car (with the exception of the Schnitzer stuff, as I need to speak to a Sytner dealership for that). They did give me a full list of ordered options that were put on the car, and by the looks of it, it has everything!
It also included screens in the rear headrests, a 6 disc DVD changer in the boot and a second freeview tuner (these are the things I'm having trouble with at the moment).
As far as I can see, the Schnitzer bits are:
Wheels
Lowering Springs
Exhaust
Rear Spoiler
Wing Mirrors (with Carbon bottoms)
Carbon Grill
Front Splitter
Silver lower grill
Titanium Carbon interior trim
Titanium Carbon steering wheel
Perforated Leather (apparently it's Schnitzer and slightly different)
Hand Brake lever
As you can see, I'm an expert when it comes to M5's.
