As far as my vehicles go, I use a creeper to get under them. The creeper I have has an adjustable head and back rest so that I can angle up and work. You have to remember that the lift can stop at any height since there are no pre-set lock positions due to the screw design (like a scissor jack). So, you can adjust the height to whatever is comfortable for you to work at.
I do have three sets of cross bars. The one set covers all of my vehicles except the Odyssey. I tried several different ways to lift the Odyssey with the smaller crossbars, but the only SAFE way was with the longest crossbars. I figured that the cost of the extra crossbar was nothing compared to getting hurt or bending something on the Odyssey because of "creative lifting." Right tool for the right job prevents injuries. The little crossbars pictured are handy for using the EZcarlift as a lift table. I can service my snowblowers and will soon be trying to service my garden tractor. You can also use it as a large sawhorse or anything else that your imagination can come up with.
I can say is that I use my EZcarlift all the time. It takes the pain and strain out of not only mechanical work, but waxing all of my vehicles as well. It is a lot easier to wax the lower half of your vehicle when it is up in the air. I am very happy I purchased the EZcarlift. I will advise you to get a good 8 amp drill to run it, especially if you have heavier vehicles like my Odyssey.
And if you have an questions or concerns, Boytcho answers the phone himself when I have called. How often do you have direct phone contact with the owner of the company?
