For this list I would

 

2015 GT3, delivered Dec 2014, 12,000 miles, 3 track days and lots of spirited driving, stock car, no problems.

 

2015 GT3 "F" code, build completion 9-23-14. 14,400 mi non-track/ 1600 mi track. No mods. No engine issues (thermostat replaced at 7500mi.)

 

Anything that changes the original parameters out of the factory should be considered a mod. IMHO.. Granted some changes could be major others not.

 

2016 G engine, 3500 miles, Sharkwerks center muffler delete at 3000 miles.
No track time (yet), no prob.
...Just had to have the engine removed to repair rodents damage to wiring harness... Thanks Geico and Fremont Fletcher Jones for taking good care of me.

 

14 with 14000 3 track days now. But misfire code did happen at 10k with 2 track days and a lot of spirited driving. Engine was rebuilt.

 

Mine was a 2014 with 7000 miles 6 track days/ weekends. Sharkwerk exhaust. Never skipped a beat.

 

'16 w/ 2350, G engine, no mods, properly broken in miles, no track time, & no problems.

 

2015 F engine 12000km no track,runs great changed oil at 3000km hasn't burnt any oil since first oil change.

 

You should add motor number or build date. E/F/G is not meaningfull because changes are made during the model year.

 

July 2015 RS, 5000 miles/2000 on track, one oil change at 1000mls, no issues but drinks oil like Oliver Reed.

diagnosed/repaired.
