fearsom,
A detachable steering creates a good news/bad news situation. It makes for more room for ingress and egress--don't you like those big words?--but you give up a "grab handle" to pull yourself out when it's removed. Similarly, the steering wheel is handy to grab hold of when sliding in. I find that the biggest advantage to having a quick-release steering wheel is when working in the interior such as the pedal area or under the instrument panel.
Good Luck,
Tom
