Finally got around to using my scissor lift jack - well impressed! It takes practice to find the centre of the car, weight wise - I was about 4 inches too far forward, but was still able to lift/tilt by hand to get jack stands under the rear.
Images below are from my garage at about half lift, after draining/filling the diff. Excuse the mess!
Note the old bonnet cover - fantastic for laying on!! SO comfortable!! ;-)
£429 + delivery, but bought on an ebay sale discount day so I got it about £50 cheaper I think.
Pro's -
lifts very well
Easily fits any of my cars on the adjustable platforms
very stable to a good working height.
Low cost.
Cons -
Advertised as able to lift using drill power - my battery drill did not have the oomph to do it so relied on 14mm socket and a ratchet, took ages but worked really well. (Council garage no power)
**There is a front and a back, ie to drive onto it, otherwise it will roll away from you... the mechanics/driver should be furthest away as you drive onto it.
You really need a ramp - I used 4 scrap pieces of 8x2 laid at front and back to reduce the step up.
Sadly, to do the sills, I would need to strip them down before lifting as the bolts are covered by the lifting platforms... as previously mentioned - an extendable platform to reach the jacking points would help with this.
Verdict - excellent piece of kit! Definitely recommended.
