I have had one for three years. My answers in order
1. Definitely
2. Not more room but much easier to work on - in particular the underside (duh). I bulit my car before I had the lift, them my wife's car after & having the lift was a real benefit
3. Yes Keep in mind that the items you are working on are a little higher than the runners. I have a little taller ceiling and can lift the car high enough to make it tough to reach some items. Of course the runners do get in the way some and you need to jack up the car to remove wheels.
4. Use it every day - my car is parked under & my wife's car in on the lift.
5. Most cars will fit under - big suvs and/or pickups will not. Width is not a problem, watch the mirrors backing out.
