I bought a cl500 pre facelift back in 2010, mainly because of the big discount, and I was a bit sick at first but it was only a minor facelift and very few people could notice. This is the same really, not a great deal different. Imo.
For me I admire the steady evolution rather than revolution of Mercedes design therefore to all but the knowledgable eye it does not shout your model choice pre a facelift is out of date.
Modern car design using advanced moulding and machining techniques giving scoops, trim additions and sometimes curious angles lacks the purity of simplicity demonstrated by earlier SLs like the Pagoda.
However to my eye anyway it shows excellent evolution as the car has to develop to meet our motoring demands and driving conditions today.

Active Brake Assist, known as COLLISION PREVENTION ASSIST PLUS in other model series. In addition to radar-based proximity warning and braking assistance by Adaptive Brake Assist, this Active Brake Assist system carries out autonomous braking to reduce the danger of rear-end collisions. If the driver fails to act when a risk of a collision is detected, despite the warning lamp in the instrument cluster and the intermittent audible alert, the system will initiate automatic braking.
