I picked this up a couple of weeks ago after being stuck in the planning stages for a year. My wife finally ordered it to shut me up. I had a pretty specific list of requirements covering mobility, safety, and versatility. I had to be able to move it around. It will stay outside, under cover, and will be moved around as needed for various jobs. It is ALI/ETL certified and has some fairly idiot proof safety features. And I can lift any of my cars from the ti to the M5 to the big 2500HD crew cab Silverado.
