Had the same problem when I got my Boxster. If I sat in the seat and tried to swing my legs under the steering wheel, there wasn't enough room to do it without mashing my leg into the steering wheel. I finally figured out that if I stick my right leg in first and position it under the steering wheel, and then slide into the seat, I didn't have to contort my right leg to get in. Takes some practice to do it gracefully, but after a few tries it gets to be normal procedure for entry. I'm not 70 yet, but I hope to be driving my S when I do get there, if I can still get into it.
