Expectations versus reality in Open Discussions Posted February 15, 2017 Those observations are pretty spot on, old Zs are loud, smelly and you can hear everything going on under the car. All of my Zs have been like that and I have had several. The only thing that would concern me is the steering, unless you have really fat sticky tires it should not be heavy at speed. Even with fat tires that does not sound right. I had a ton of drive train noise in my last Z, ended up being both the trans and rear wheel bearings. But even after fixing those it was still loud.
