I considered buying one of these before. It'* still in the back of my head as an idea but I didn't buy one yet:
This would make dropping the drivetrain on any front wheel drive vehicle rather simple and safe. Many years ago, I had two Buick Centurys in the garage side-by-side to do a swap with minimial tools/lifting equipment. Both drivetrain assemblies were dropped to the floor, rolled over to the opposite car and bolted right up. This lift would have made things very simple.
The way we did the 97 donor car was with an engine hoist chained to the front bumper. Not exactly the thing to do if you are concerned with the body but an effective way nevertheless. As Bill described above, it was a bit easier to separate the motor/trans from the subframe and install them separately. subframe from the bottom and engine/trans from the top.
