If the car has nice paint, 2 people will make it easier but you can do it by yourself with a floor jack. Big key to remember, bumper needs to come back as it goes down or it will catch on the 1/4 extensions. A few layers of 3M masking tape on the paint in the areas of the bumper, as well as on the edges of the bumper near the paint will be added paint protection insurance.
