I've had one of the eBay ones for a good few years now, it sits in a 6" pit in the centre of the garage because at 500Kg even with wheels it's almost impossible to move easily. Great tool not just for the mini but any other car too, makes servicing, brake work of even a clutch change much easier.
I heard lots of comments about access and to be honest it's normally from people who have never seen one in action. You can easily position the car in a way that allows you get get to what you want.
I've kept the arms, fronts go just under the 'tails' on the front subby and the backs on the rear subby. Even with 1" spacers the inside of the rear wheels can catch on the frame of the lift, but that's once again if you do not position the car correctly.
If you buy one get hold of an old wardrobe door mirror (the longer the better) - stick it on the wall in front of the lift, it allows you to position the car much easier on the lift.
I agree a two post is better, but you need the height and at least 8" thick concrete under the towers and where the stabiliser arms run(each side at the bottom of the towers), fine if you are building your workshop from scratch but a pain if the floor is already in place.
Stick 'domcr250 scissor lift' into Google and hit the image button, you will see mine on my lift before I stuck it in the pit.
