Premier Autotune Workshop
“Genesis was transparent with me, and answered all my questions, they weren't trying to sell me anything or push hoists onto me. They could see my plans and what I needed for the future for all the types of cars I service. And they provided me with solutions for what is going to work for my workshop and the future. I’m confident with Genesis Equipment and the BendPak hoists they’ve supplied me”
