The height can't be adjusted, my B8 S4 gets up high enough for me, possibly the wheels are 3" off the ground.
It is too low to get all the wheels up in the air on my wife's 2015 VW Polo 6C, but initially I lived with that and just increased the height on the front by lifting it slightly off the font stools to remove front wheels and then drop it back down onto the stools. I have now made up 4 wooden spacers that fit on top of the stand tops, that works okay for the Polo, my daughter's SEAT Leon Cupra can use them when it gets its wheels swopped over Summer<>Winter.
Price, I'm not sure but very high, when I first looked at this, I knew that I needed something to lift the B8 S4 up and onto, I joined a Porsche UK buying group and we got discount, the air freight from USA was dirt cheap, a special offer at the time.
I'd guess, and this is only a guess, without checking John's prices, that a pair would cost £500 and so a full set of 4, ie 2 pairs, £1000.
There should be someone in Europe making something similar, it is a no brainer really, I was very disappointed at needing to join a Porsche forum and then join a group buying them in from USA, but needs must I suppose. They stack up one on top of the other and for convenience I bought a tyre/wheel dolly to stack my wheels on when I'm working on any of my cars, so then I can move them around easily when I need to clear a space, when not working on cars these Jackpoint jackstands are stored on that dolly, again to easily make best use of my double garage when using the workbenches for other non car jobs.
