Last time I did one on my own with an engine crane, I unbolted the engine from the subframe, I then split the offside hub bottom balljoint (I think, it's the longer one) started to lift the engine. I slid back the rubbers on the inboard pot joints & then as the engine was going up I somehow managed to get the drive shafts out of the pot joints, DON'T remove pot joints from engine or you'll have oil everywhere. If you're going to lift the subframe into a car/van later it might be easier to take off both hubs & pull the driveshafts out of the subframe, it'll be easier to lift the engine as well. This is all with a manual box, I have no idea if a auto has the same pot joints/driveshafts. How did the person you're buying it off get it out of the car, do they not have a crane you can borrow? When I picked my last engine/subframe up the seller had a crane & we just lifted it up & put it straight in the back of the Berlingo, problem was back at this end as I'd lent mine out, so all I did was tie a rope on & drive forward & dumped the whole lot onto a pallet.
