The F10 M5 was also used as a Nürburgring Ring Taxi.
My M5 was a steal, if you want to know more about it, you can check out my full YouTube review on it here add link later.
Due to the presence of the battery, luggage space is reduced from 520 litres to 375 litres.
Beware of increased brake distance.
I enjoyed being able to use my M5 as my daily driver for a few months after I toned down the tune a bit.
It knows which units need to be programmed with ignition on and which with it off.
