Background
I got my 2012 Z Sport/Touring/Nav in the summer of 2012 as a more reliable daily to replace my old daily turned project car. I had a Toyota MRS with a 2ZZ engine swap, 6 speed manual conversion, and being prepped for a turbo. I fell in love with the Z so I sold the project car and started modifying my Z. I drive the Z as a daily, ~35,000 miles per year, and it is under an extended warranty until 120,000 miles so I stayed within the warranty with my modifications. In the winter of 2014 I ordered a 2015 Z Conv/Sport/Tour/Nav/AT and it arrived about 3 months later. Below I have tracked my repairs for fellow high mileage drivers. As the 12' Z got into the higher miles it began to have more and more frequent problems so I traded it in on a GTR.

Miles & Repairs
All maintenance and repairs are done at the dealer I purchased the car at. I do all of the milestone maintenance and use synthetic oil.
The Clutch, Flywheel, & Slave Cylinder were replaced at a reputable shop, that I have used for other cars, because the dealership was unsure about installing aftermarket parts.
I do my brake & suspension changes.
