Just tell me then as a mechanic what would I check and advise on by sticking my head under the wheel arch and looking at a coil spring apart from it being broken?Sorry ,I've no idea the point you are making . Springs are often colour coded ,some car makers do 8 codes on 1 vehicle depending on spec .Others do 1 across the range .
Manufacturers will then do a compromise part number to cover them . You can get two new springs that look different but sit the same on the car . Less/more coil, different wire diameter .
Unless you go to dealers for the exact oe spring all the springs will be made for the job but aren't necessarily exact . Even dealers now due to price pressures offer non oe stuff in " value " ranges in dealers boxes
Springs dont get changed because they lose bounce so why change it because the other side snapped ? Yes they soften over time but not massively .People sometimes swap a pair out for heavier options if towing etc . The fact is the car has had a life and owners may not know how old anything is under the car .
That's where a mechanic would check and advise . The 1 thing i know for sure is a pair of springs bought isn't common . The broken part gets replaced
