While in for a service I was tempted. Got the new car last weekend. Including the safety package.
Quick comparison after a week
The new 6 seems a slight bit better at handling the bumps, even with the 19" wheels so that's a plus.
Stereo/sat nav is much quicker to load. There is less in the NAV set up. i.e. can't change the map colours, voices etc. I think I preferred the TomTom functionality and the way the maps zoomed in at roundabouts etc., but as I'm getting used to it and it works fine. Ipad loads up much quicker and remembers the settings, no more putting on shuffle everytime I start the car.
The heads up display might help if it was centred. Mine is off to the left and the speed signs hang off the edge of the little screen unless I lean to one side, so it's going back to the dealer to get it centred. You can adjust the height but not the left-right position.
Same engine and I'm taking it easy so I can't fell a great difference in that.
I find the Blind Spot Monitoring and the adaptive headlights really useful. Not really been on the motorway so lane keep assist hasn't been that useful yet.
Electric seat adjustment is easier but once it's adjusted I don't use it much. Heated seats and steering wheel are good in the cold.
Inside is much more luxurious, leather seats and the trim are higher quality.
Noise reduction is a bit better too.
I really loved the old car and this is well just better.
Still the best looking car in the sector.
