Well as someone who has an E-Class in the family and drives it on a daily basis, I can't agree with their "lacks personality" assessment. The E-Class has personality, but it isn't of the sporty nature of the 5-Series and perhaps the new XF. Just yesterday I was in Freising all day since I had a day off and I drove my dad to one of his annual beer drinking conventions (don't ask

). On the way home my dad was literally passed out and snoozing in the front passenger seat with the seat reclined all the way to the rear. I drove home in a somewhat sporty yet elegant manor and I found myself still enjoying this car. It's not as sporty as the facelifted W211 E-Class but it feels plush, sporty enough and is very comfortable. I'd say this speaks for itself. The engine is a bit on the rough side compared to current MB 3.5 V6 but its reasonably refined and has a nice sporty snarl to it when pushed. I don't know, but to me this is a nice personality.
My biggest problem with the Jaguar XF is that it looks like a Lexus GS copy from several angles. I don't think it was blatantly copied, as such styling cues are also appearing on other cars and just seem to be a natural evolution on many designs, but in this class with the Lexus GS being a close competitor, I find this a bit alarming.
