Every morning I start it up and let it warm up - I can hear it going through it's warm up tune as I do my teeth - makes me grin every time.
It's incredibly comfy and the ride is beautifully supple. The seats are gorgeous and mine has the bmw individual Hi-fi which is epic.
I always drive it in manual - either paddles or stick - auto really is as bad as they say! Thing is It's not a chore and you're connected to one of the greatest engines ever built!
Took me about 6 months to learn to pull off smoothly but now I can town driving is a doddle.
Obviously 11-13mpg round town isn't great but you get used to it and I've bought an xc90 on lpg for family work so M5 is down to my commute and playing which is maybe 100-200 miles a month.
When you want it to be it is epic though! Go go out regularly with a mate in an f10 M5 and obviously he roasts me for low down grunt, but I've noticed he often has his window down so he can hear the V10!
If it's not coming across already - I love it! Was really worried it wasn't going to feel special every day, it hasn't disappointed in the slightest!
