OK, so I might be a bit biased as I have just picked up my E63 (latest model).
Previous versions looked dated by comparison and this model now brings the E class bang up to date. I personally think it is gorgeous.
I was looking at the previous version and wasn't sure I liked the look. I then got an offer on a 3 month old car, went to view it, and fell in love.
It is a stunning car, don't know if that is because it is an E63, but I assume that as it is so understated that other 'E' models won't be too far different.
Cheers
