SLS/R197/C197 AMG: Sitting in and out, closing door

Couple questions:
I'm a stocky 6-foot 280 pounder and am concerned about the ease of clearing those wide SLS rocker panels while getting into the drivers seat. For comparison, I'm very uncomfortable trying to draw my legs over the similarly wide rocker panels in the newer Viper GTS Coupes (partially due to the low head clearance which will be a non-issue with the SLS gull opening).
Also, since I have wide shoulders, I'm equally concerned about whether Ill have to twist my left arm & upper body uncomfortably to close the door while seated?
I had the opportunity to sit in Frank Lloyd Wright's MB Gullwing a decade ago and recall it was uncomfortable getting in and out of the drivers position too.
Thanks in advance!

The good news is my local NY dealer saved me a trip to Boston, he has a pre-sold iridium silver/red SLS I can check out in 2 weeks.
