It is a facelift but I do prefer the pre-facelift as it's a bit more squared off. Plus I'm a fan of the older tail lights. What I'm looking forward to the most is the sleeper aspect. It should at least keep up with more modern AMGs and Ms so for some 20+ year old Mercedes I don't think many would see that coming!
By far one of my most notable memories in the E60 was the second or third time I drove it. No plates or trunk emblem yet, just driving late at night and stopped next to a GLE53. We both launched at a red light and I was about a car or two ahead. Granted GLE is the heavier vehicle and he probably didn't have time to use the fancy launch control but the raw power of the M119 6.0L caught us both by surprise. I had a huge smile, amazed how noticeably quicker it was compared to a W210 E55 whilst he and his wife later pulled up also laughing that a 25 year old station wagon did that.
