Thanks for the tip - I'll see if this test gives anything tangible
result-wise.

Don't really have anything level around here. We don't have a garage or any
flat concrete slab.
But if I get to such a spot I'll do some measuring.
I'm leading towards suspecting both rear springs since the car has a towbar
and it's quite an old towbar (going on how much rust it's bottom surface
has). So a previous owner may have hauled trailers around with the car,
and/or loaded up the boot space with far too much weight. 8-)
