I've got an 02 S60 with about 200k miles. Never had struts or anything replaced. I went to get an alignment at a tire shop and they told me that I needed new struts and coil springs because the coils are way too close together. I took pictures of what the springs look like with the car on the ground. I know I need new struts for sure but I heard it's rare to have to replace the springs unless they are broken. Just not sure what normal springs are supposed to look like with the car on the ground.

 

I think I also need new spring seats. Not sure if that could cause the problem as well.

 

If it was mine I would be doing springs, spring seats, upper mounts, struts, the whole 9 yards, assuming you intend to drive it another 50K+. There's a reason many cars have complete assemblies available, because if the OE makes it 150K+ then the springs aren't anywhere close to doing their job right anymore either.
