Hi Mark,
I think these questions have been answered by Glos Guy, myself and others. 🙂
Haven’t seen any Sports around, let alone ones to test drive. The eDrive 35 M Sport is the only one I would consider as giving a fair comparison.
I really wouldn’t want to try an M50, it would give a false impression!
Not that the 35 isn’t ridiculously quick. Even in a car weighing 2.1 tonnes, 286 electric BHP is amazing .
As Glos Guy says, aim for 15% off optional extras.
We once achieved 50% off the Comfort pack on an Audi Q3, but that was in a stock car in very different times
