I'm one of the few who've owned my NX since it was new. I currently have 145 000 kilometres (about 90 000 miles) on it. It's a daily driver, including winter driving, so it's rustproofed annually. Even so, I did have to replace the rear strut towers as the rust got them. Make sure you check your car - pull back the carpet and spray them well inside and out with rust proofing.
Over the last three years I've been doing some upgrades. These include the basics like advancing the timing, Tinted Windows and new wheels - Motegi RT5 with Yokohama AVS ES100 195/50/15 tires. Since my intent is to have a good handling car, when the stock suspension started showing it's age I replaced it with Ground Control Coilovers, KYB AGX struts, Eibach Springs, and an ES HyperFlex Kit. I've also installed Shigspeed's Rear Pillowball mounts, Active Tuning Rear Strut Bar, Ractive Front Strut Bar, and just last week a used NX2000 rear sway bar (and the ES bushings that obviously wouldn't fit the OEM sway bar). I tried a drop in K&N filter, then a Ractive WAI and am now using a HotShot Cold Air Intake with an AEM Bypass Valve. Rain or snow, it's been fine. A year ago I installed a HotShot Header and a fabricated 2" stainless steel exhaust with mandrel bends, a SS 24" XL Magnapack and MagnaFlow Muffler. I've read on here about the resonator reducing noise, I'm not sure that is as much a factor as reducing interior resonance between 3 and 5 thousand RPM. I could hardly hear myself think when I tried a small resonator. Finally I have a B&M Shifter and, to be heard in emergency situations, NISMO 350 Z dual horns.
Adding the sway bar has tightened the car up that little bit extra, but now I have to find what part of my exhaust is touching. I've got a rattle since doing this that I need to find.
Hope you enjoy the pics of my car. Thanks to everyone here who's answered questions for me - whether you knew it or not.
