Looks like you could do with a "touring" version mate
When did you get back? I was at the Alpina factory last week so it probably wasn't me on the M25 - common as muck these things are around London
Sounds like a great trip - hope to see you again soon.
BTW, all the GPS detectors go bonkers on the M25 (especially in Surrey) - I think they vary the locations of the active Gatsos and the databases can't be 100% certain. Fitting a radar detector/radar head will allow you to know which ones are 'live'.
