A big thank you, once again, to this forum and everyone who has been helping. We'll have further updates in May and August.

With more participants, we could provide more precise information and cover all model years. we'd especially like to have a result for the new 370Z--but need more people.

Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

As always, more participants would be helpful. Updated Car Reliability Survey results in May, with a preview for participants soon.

Signed up with my 2003 track, 136k miles Thanks

 

Thank you, I appreciate it.

Updated results in a few weeks.

We'll be covering every year of the 350Z, but aside from the 2003 the number of responses is too low for a full result.

signed up my 03 Touring 6mt

 

Just signed my Red 2003 Up.

 

for ***** and giggles i looked at this site, and i do not even see the 350 z on the charts at all.

Oh wait you have to join? c'mon info should be free to see for all.

 

Results based on more than 25 responses are viewable by all visitors. All reliability stats for the Z have been posted regularly to...this thread.

If all information were viewable by all visitors, people would have less incentive to participate in the survey, and we'd end up with much less information.

Paradoxically, we end up with more information available to all visitors by requiring people to join to see everything.

ok, i signed up my 04.5

 

Thank you, I appreciate it.

One note: because more extensive changes were made for 2005, I've been changing the 2004.5s to 2004s. I do record when I do this, so it can be reversed if we start tracking half-years separately. Currently they're included with the following full model year.
