I just went through this with my 2-post / 3-car garage. It really helps to get the size specs of a lift that meets your requirments and lay it out on graph paper with your shop measurments drawn out. The narrowest 2-post I could find is the Mohawk A-7. Thats what I went with and its a total beast. I love it.

I would put it in the single bay if you have room. As mentioned, you need about 10-12 feet for the max width of the lift. But usualy they also require being placed about 8-12" min from the wall. If you have at least 3 feet from the edge of the garage door cut-out to the wall, and another 2-3 feet between your single and double door you probably can swing it without encroaching on the 2-car space. If you put it in the dble car space it will certainly take up both sides of useable parking space.

You also need to consider that the posts cannot be within 12-24" of a crack or floor seam (specs vary with manufacturer). Also the electric supply and the fore and aft location of the posts needs to be figured out. When it comes down to it, there are a lot of considerations to go through before the lift gets put in.
