I brought this a few weeks ago but it doesn't really go high enough for my to get under the car. Does anyone know of a reasonably priced (locost) one with a higher lifting range?

I bought this model but branded as Halfords a few years back to lift my Rover 800 it has been very good.

I bought a new jack from Costco a couple months ago. Was a bit more, from memory at about £60. I had the same one as you and had the same problem getting height, but also getting low enough. My new one goes under 91mm.
