Cant imagine not having mine, makes everything easier. I do not have a huge garage just a typical one. If you have garage door openers you can opt for the tracks which mount on the ceiling and the opener drive motor that mounts off to the side which will give you more height. I do not store anything underneath of my car so I didnt need to do this, however, if I wanted to do so I would need to relocate the tracks/motor as my ceilings are 9'
I would also recommend the optional jack which slides front to back along with drip trays to protect whatever you put below
