I am in the market for a MB performance convertible. I keep going back and forth between AMG CLE 53 and AMG SL 63. I love the sound and performance of the SL, but the price and fact that no adult (sans a dwarf) could fit in the backseat. The new CLE 53 can fit adults in the back and is not nearly as expensive….but loses on performance. I have never owned an MB, so appreciate any thoughts.
