One of the reasons I went for mine was the access to the underneath when it's on the lift. Using the bigger lifting blocks means the is enough access to do things like full exhaust and prop removal as well as replacing the brake pipes running the length of the car at the side. I've also managed clutch changes on Zeds and other cars. I've just sorted a full height 2 post lift for the unit, but will be taking this too as it's so handy.
