If there are any Z's out there with over 15 to 20,000 miles i was wondering if you have noticed any changes in the cars newness like for example steering getting looser, car wandering a little more, squeeks and rattles,vibrations...etc. Or does it feel like out of the lot still.

 

30,000 miles and tight as a drum. Feels like new.

 

I have a 2003 Track with 9000 miles on it, and I've noticed some rattles in the interior. For example, my sun visors rattle, my rear view rattles (sometimes) and now there is a noise coming from the instrument cluster. Mechanically, everything still feels tight.

 

I've got a 2003 performance with 23,000 miles. A couple of rattles and driver's side window just quit working. Other than that, body and engine are tight.

 

Z #1409, and I don't drive much. I'm just at 10000 miles or so, but I noticed around 8000 that the car was feeling a little looser, which was better. Around 6000 miles I got an annoying cracking sound coming from the back whenever I hit a bump, and I think there's a dash rattle. The A/C has always made funny chirping noises as the air comes out of the vents.

 

25K+ My Z still feels like new, other than it shifts smoother and the brakes don't dust as much (still on original pads) - - I guess it depends on where you live (ie: road conditions) and how you drive her - I drive agressively enough to enjoy the Z but I don't beat it.

 

22,000km (not miles) and I've had the drivers auto window mechanism replaced and diff replaced - that's what warranty is for. A few sqeaks and rattles in the cabin, but nothing overly annoying.
Love the car more each day.

 

20,759 and a couple of interior rattles in the dash but easly fixable as soon as I get off my a$$ and do it. Engine, trans., etc. still running GREAT!! No complaints here.
