Researching spec levels?

I'm trying to find a comprehensive list of the options you could get on e60s and which spec levels came with which options as standard. Having done a bit of searching I keep coming up with American specs which aren't much use so does anyone know any sites that have the specs of Irish or even uk cars?

Thanks in advance

Here's a 2008 BMW e60 sales brochure for the UK which has equipment options identified:
