I had two lifts and it worked but was a little too crowded.
I did not have the side mounted opener which made it tougher to store two cars, but my wife's Solstice is so short the garage door was never an issue. I went back to one lift and now I can bring my Escalade in and wash and vacuum it much easier now.
I love mine! Definitely worth it to have it. It's a Specialty Automovice Lift.
The car garage has 12 foot ceilings so I can put the lift all the up and I can walk under it (I'm 6'3").
