Thinking of getting the Ultimate spec simply for the electric seat, my wife has Spina Bifida so is very short. Our hope is that due to what appears to be a very large range of adjustment on the electric seat she can fully lower it for getting in / out (also maximising space for wheelchair load) and then fully raise it to get a suitable driving position without needing her bolster cushion. Currently uses a C4 Cactus diesal and it would be great to have a level or levelish transfer from the wheelchair.
