I know what you mean about easy in, tough out. I drive my Cobra to work nearly every day. The folks by the first floor windows get a kick out of watching me pull myself out of my Cobra. (I'm 6'4", 275 lbs, CR Cobra.)
You sit down in the Cobra instead of up on (like in a truck or SUV). An MGA is about the same sort of thing. Heck, so is a Formula Ford. Easy to get into, a bit of an effort to get out of.
Me? I just put my hands on either side of the Cobra body behind me and push myself up and out of the Cobra. I ought to start getting out of the car without opening the door ... that'll give 'em something to watch!
