Yes looks like it, if you go to view one another way of checking is by lifting the arch up and letting go, it should compress a little but if it feels really loose or saggy then it's on its way out or dead,
You can get replacement shocks for about 80 quid a corner and around the same for springs, Mr b has a thread on here somewhere with part numbers,
If you go see one and put an offer against it i'd try and get 200-300 off or have the garage replace it before you take delivery
