So what's the difference between them?

Pretty much as expected - CP has better exhaust noise, tighter handling and a slightly bumpier ride. Cosmetic wise, the marmite wheels split opinion - everything else is doable on the standard car (which is shown here - shame I didn't take those carbon mirrors!!).

Verdict - for me the CP takes it but I could understand with anyone disagreeing.

Sorry for how long it's taken (work very busy), the lack of outside shots and fact my microphone died! Weather was horrendous to start with and then I had GoPro batteries fail on me and then the mic. Such great plans..... Will do better next time - already filmed most of next one.

A huge thanks to Chris Rooney at Chandlers Brighton for arranging the loan of his own demo Dakar Yellow M3 (that is up for sale). For more details on that car - http://bit.ly/29rIp2i

Lastly a big thank you to Zach and Charlie Lower that shot a lot of the outside stuff. Was a bit of a challenge with the weather (couldn't get quad up at all) and shifting cars around - lots learnt for another day.

Thanks for watching.
