I plan to buy a set of coilovers for my 95 240 but I think i'm going to search for a used set. What would i look out for? Blown shocks? Bent struts? How do i check for those? What are some standard things to watch out for with most used coilovers? Thanks

 

You answered your own question.

if there is oil over the unit then they are bad.

 

well, I figure if someone was to sell bad shocks they can just clean the oil up. But is there a way to test the shock?

 

Well try to compress them if you hear a whistle or watery sound (hard to explain) that means the seals are blown.
