I've had a few E70's Msport's and currently have an F15 hybrid, but there was a facelift sometime towards the end of 2010 which apart from the upgraded bumpers and newer lights, the 3.0d increased to approx. 245hp and they came with the 8-speed auto box and the two combined were a big step over the non-facelifted ones.
Also the rear airbags in the suspension generally need to be changed every 75k miles.
I really enjoyed driving the E70's, good luck with them.
