C36/C43 -- 4 seat or 5 seat?

[sixto]

Sorry for the non-tech post. There should be a stupid questions forum for questions like this.

Just as 500Es are becoming affordable, I was disappointed to learn that it's a 4 seater. There isn't even a habitable surface like in the 2.3-16. Since the C36s and C43s I see are moving too fast to get a good look, are they also 4 seaters or are they 5 seaters. Kinda pointless in a smallish car, but such things matter to me. And does the sport package such as on the W124 and W210 delete the rear middle seating position?

Thanks,
