I won't argue with you on that. But there are some things I faced with my setup that might be useful for Michael. I had the pillar in the center of the place, which limited my at-the-doors space pretty severely. So I put in work surfaces that swing down so that I could roll the car out and have useful space that wouldn't be available otherwise. You could even store the bikes along the wall above that fold-down (or fold-up) bench.
I think in Michael's shop, there's a lot of space up high that could be used -- and some storage down low -- specifically on the passenger side -- that might work better if it was opened up (with the storage removed).
A bench at the nose-end of the garage might be the best place for a fixed work surface. You could put some storage up above.
The bottom line on Michael's place is that he's got '10 pounds of Porsche awesomeness stuffed into a 5-pound sack.'
I don't know if a shed would fit into his situation, but it would be great to get a lot of the non-automottve storage out of there. It'll always be a snug fit, but the shop could be tailored to the car a little bit more.
