I also have the MD6xp. Actually, I have two. First one I bought in 2006 when I was doing a lot of work on new MINIs at my ex's garage. Luckily, back then it was about $1500. A few years later a car forum member in MD was moving and was selling his older and well used lift for $1000. I managed to get it home with my minivan.
Six years ago or so, another forum member in CT was selling his Max Jack for a really good price. While I don't have a place to set it up yet, the price was too good to let pass (even better now), so I had to buy it.
A few years ago my ex was upgrading her Quick Jack to a newer version, so I added that to the collection...
Did I use any of them when I swapped the tires on the MINI? no... the regular floor jack was faster...
When I swapped the wheels, I noticed one of the concentric rings was missing. Huh... but I was able to install the wheel without and after a test drive it seemed fine, so I figured I'd look for one at Carlisle. All the while thinking, "I know I've seen it somewhere but it didn't register what it was..."
Then as I was packing to leave this morning, I found it...
So before I left I disturbed the late sleepers in my neighborhood with the impact gun as I pulled the wheel off to get it on.
Made it to the show field.
Parked with my Spitfire friends.
