Just go to a couple of your local dealers and find out name/contact of whoever does their installs/maintenance--

With all the dealer shutdowns in past few years these people may even have some high quality lifts available---there is a BIGGGGGGG differance in types as to symetrical, assymetrical arms and heights they lift. You will need 220 volt.
If you are only lifting regular size car, 7000 lb will do, suv/pickup 9000 or 10000lb.
Rotaries are USA made, some others are furrrrrinnnn!!!!!

If you can find contacts from dealer inquiry you can make a deal complete with install and will be good contact for any maintenance needed.
I got my fairly late Hunter 4 wheel alignment rack that came out of Caddie dealer that had to upgrade because of LENGTH of suvs (whatever Caddie calls the Subruban)
