136k miles, 2013 G37 sedan. One cat went bad at 80, replaced under warranty - other than that, zero issues. Go through lots of tires though :-)

 

Best it all day long, red line most of the time, no issues, regularly oil changes every 4K, it’s bulletproof

 

My 2K7 G35X I've put 60k on it.

• Replaced both front lower control arms
• Replaced one seized rear caliper

Other than that, it's all typical wear and tear items like brakes and tires. Everything still works, and car drives like most new cars. I did take it in for it's 130K.

 

I had a 2010 xS that I purchased new and put 84k miles on it before I sold it last year. It was a great car. The only time I needed a tow was when one of my front brake lines failed. Even with all the bolt-on mods, the car ran great aside from that. Even Chicago winters couldn’t stop it.

 

Not really reliability, but I've put only about 31k miles on my 2013 and the driver seat's starting to look like hell (creases). Not too thrilled about that...

Perfectly sound mechanically, though.

 

I have 87k on my 2011 (non-sport) and the outer lower bolster seems to be a weak spot on these vehicles. The foam is losing its shape allowing it to sag and show creases - my plan (someday) is to pull the lower leather and reinforce the foam in this area to make it look better.
