This is one of the hardest cars for me to get into or out of I've ever used, whether I owned it or was just a passenger. The last one that would take second place was the early 70's 4-door Ford Torino. The back door was so small, and the car was bigger than the 'Bu!
However, if I move the steering wheel up and forward it gets easier, but I'm still lifting myself up to get out.
My seat: I've played around with low-slung in an effort to get the lowest CG, and I've lifted it to the point where I'm nearly scraping the roof with my head. Getting out with it higher is quite a bit easier, but I run the risk of bumping my head getting in or out, 'cause the seat keeps me from being able to dip my head low enough.
And I'm 5'6", so it shouldn't take a freakin' barn door to make it easy, eh? I think in an effort to make this such a safe car they made the safety cage openings smaller to keep them stronger, but something had to give.
