Rut, I see you've asked about 4 post lifts (over on the Spridget forum). Thought I'd give you some thoughts on why I chose the 4 post....and to say thanks to malbaby and Kevin for their comments.
Wow..what a garage and contents.
Hey thanks guys. Glad you approve.
I went with a 4 post lift and two rolling jacks. I chose it over a 2 post because of the variety of cars that I would be lifting. I couldn't be more please with my lift and have no regrets.
The rolling jacks aren't cheap, but boy are they a pleasure to deal with.
You can lift one end of the vehicle or both...depending on the task.
As was commented over on the Spridget forum, suspension work can be problematic, but it's not impossible or difficult (here I'm re-bushing the leaf springs on my '55 F100.
Makes changing oil a pleasure (no more creepers).
And the feature of additional parking when needed.
