Howdy all....Always had my eye on the CLS, mainly down to the gorgeous(imho) lines and looks, could be getting a bit closer to owning one and i'm pretty much set on a 55 (M113) and was just curious, why are they quite a few grand more expensive than the 500, the 500 is only missing the supercharger after all! there seems to be a raft more 500s up for sale at reasonable prices than the 55s is there some reason behind this i'm missing?. owners opinions on both models greatly appreciated!.
