The E63 and E64 is a great looking BMW . Even when I see one in the street I stop and stare because of the design , See it with the 19" elpisoid wheels and it is a visual feast in which you do not need the all singing M6 just to grab peoples attention. Just look at those proportions and how the design all connects especially at the rear and how that roof line forms to look individual sleek and futuristic. Even though the car is now over 3 years old (5 if you count the BMW development phase) It still looks as if it was launched today.
I reckon this car will be perceived as a new classic for BMW Which is why the incoming facelift will not be drastic but subtle.
