THE ORIGINAL HYDRAULIC STYLES GREAT BUT CAN LEAK AND REQUIRE SEAL REPLACEMENT

these are a bit harder to use and smaller but less likely to require maintenance and they are cheaper
make it easy to pull a corvette into the shop, and just slide a car skate on each wheel, ,you then pump up the cylinder that closes the two parallel roller bars , lifting the tire off the ground, letting the 4 swivel casters on each car skate allow the car to be pushed in any direction.
once you get to working on a car theres lots of times that the ability to push it to a different location while the engine or transmission are not 100% functional, becomes an asset.
keep in m ind the other (cheaper ) type floor skates, require use of a separate floor jack, and the ones Ive seen that a buddy purchased at HF, are not built nearly as strong from what I,ve seen, and remember corvettes are generally so close to the floor that many floor jacks won,t clear the frame unless you first drive the corvette up on a small floor ramp, and you can,t remove the floor jack unless you place spacers or ramps under the tires (Ive got 4 double thick 3/4" 12"x12" square sections of plywood I put under the corvette tires at times just too get the required floor jack clearance.)
in fact I bought the ones I did only after seeing, how useful they were in use at, a friends, he had used a set in use in his shop, for over a year, and they were working so well, it made moving his second project car simple.
and after seeing the other type bend , at a second guys shop under his project pick-up truck and obviously being stressed to the point they looked about to fail
(they did,nt fail but were obviously bending under load)

in fact that lack of easy floor jack clearance has had several of my friends build a couple of shallow ramps that they use in their shops that look like this
depending on what your goals are you might consider a car rotisery
