The 3GT is not built on the X5 platform. It's build on basically the same platform as the 3 and 1 series.
The wheelbase/overall length vary a bit.
But it shares no parts or so with the X5 (which is obviously huge compared to these cars, and very expensive to run/difficult to park etc etc)
As for which car to choose, if you want to load large cumbersome things (like that wheelchair), or heave things, a flat loading rear door/boot is a must imho. Some cars have a threshold.
