Well, my 914 was in the shop so long, I went out and bought a Boxster. Now, looks like my 914 is coming home in the next couple of weeks, and I've got to deal with the fact I have four cars and only a three-car garage.
My garage has 12' ceilings, and it looks like to me that I could use a storage lift to stack my 914 over the Boxster (or vice-versa). I've got 98 1/2" from the floor to the lowest point on the garage door when its up. I measured the Boxster's height the other day, I think it was 45 1/2". Not sure what my 914's height is, but I suspect it's several inches lower than the Boxster, so it looks like it should work.
Anyone have experience with these beasts? This is one that I'm looking at:
