So why does the SL lose? Because it gets penalized for its price and daily usability compared to the M6. Well, it is not cheap but it is not supposed to be. Not like the M6 is a value in of itself. Additionally, the M6 will have more usability because it is based on a four seater. The SL needs to store its hard top in the trunk so naturally with the roof down it will not have as much space as the M6. Why does the SL not get points for being significantly lighter than the M6 despite its folding hardtop?
We have to disagree strongly with Autobild here. The car we would choose from a performance standpoint is the SL. The M6 may have more room in the trunk which is fine for the owner who can fill it with boxes of tissues to dry his tears as the SL leaves him in the dust where it matters.
