2013 Mercedes-Benz SL

The 2013 Mercedes-Benz SL could have been a looker, if only they chose not to mount though hideous headlights, made that much worse because they're so gigantic.  I think it's mostly the fault of the blob-like light piping / LED section on the upper edge.  If that were a thin strip on the upper edge with quad circular reflectors below it would look infinitely better.  It's a shame as it's mechanical improvements and weight reduction most likely make it a better driving car.  Pictured here is the recently unveiled SL63 AMG.  Note that the revised lower fascia with larger, more aggressive air intakes are still overwhelmed by the brutal headlights sitting above them.

Here's my quick and dirty fix for the headlight units.  Overall I think they would look better as smaller more intergrated units.

Mercedes SL

Given the nature of the SL (more of a grand touring type of car) and the extra chrome slathered on the vents, I highly doubt giant spoiler and rear airfoil are all that fuctional. And what's with the Mugan/Lumma Design random body panel paint job?

SLZ3 Widebody

A Mercedes SL outfitted with a Koenig widebody kit, which doesn't look too bad. I'd give it a 8 out of 10. But then they stuck on BMW Z3 ripoff vents behind the front wheels. That instantly brings the looks down to -457 out of 10. I hate them on "ricer" cars, so it's 10 times worse on what should be a classy, expensive car (not to mention BMWs rival).
