Anyone replaced their shocks and or struts? I only ask bc some say every 50K and I am approaching 80K Only thing, my car handles OK so I don't see a need yet. I ask bc my son's car 2005 Chevy Classic is getting new ones tomorrow and he has 87K and his car handles quite different than mine. I am sure mainly in part to the tires/ build etc. Wondering if I should think of them for my 2012 yet?
