Geez..."Just keep it"?? That means "free", right?

Getting the right spacers for the car(s) you're going to be working on make a BIG difference. Between my son and I and some friends, we have about 10 vehicles that we currently work on, so getting the right spacer for us was a big deal.
A friend and I had looked at the QuickJack over the last couple of years, but there are different models of those as well, and you have to buy the one that matches the
length of the car(s) you're going to be working on.
I don't have the "drive over" kit, and frankly, my garage
***** as far as width, so I just put the lifts on each side of the car, attach the spacer to the first side, then slide it under the car far enough so that I can attach the other side. I do that for operative and non-operative cars.
I use it out in the driveway a lot, out there I have the room to slide the whole thing fully assembled under the car.
BTW: Definitely NOT a fan-boy of either the EZ Car Lift or the QuickJack, they both fill my current need, but when I upgrade to a house with a better garage, or the room to build one, within the next year or so, I will install a proper two point lift.
