Hi Bluewolf, glad you like it.
I regret some of my DD LED strip purchases. Several have been the wrong colors, failed, or are on their way out to failing. I don't mind running wire (I consider myself decently skilled), but faulty product time and time again is faulty product. However, DD customer service is top notch so they've always set me straight.
I regret my black roof vinyl. Can hardly tell it's there except under certain light. I wouldn't buy it again had I known that. Installer was excellent though, no gripes there.
Window tint, I should've gone darker. I'm 30% and it's not enough.
AutoExe hood struts. I don't like the way their plates install. If you buy them, use loctite on every bolt, or they'll fail and bend the bracket like mine did when the hood comes down. Still need to fix that.
AutoExe wiper blades. They have wind deflectors on them, so I figured I could just flip them around for a USDM, LHD car. Wrong. They're riveted in and need to be drilled out, and rebuilt. Christ.
I regret my f**king alarm. F**k. It's so sensitive. It goes off at least once a week unintentionally. And the range is trash. But it's remote start and extra security, so it can't be too bad.
Most of my mods I've been pissy with one way or another, usually because of manufacturer error. My wheels have imperfections, BCR sent the wrong springs, DD has sent dud/wrong LEDs, vinyl wrapping wasn't flawless at first, AutoExe hood strut plate bent (better than the hood bending I guess), coilovers are a bitch, subwoofers are massive and the tweeter glue failed, etc.
Everything else I'm happy with. I definitely would've done things in a different order, given the chance. Pry would've gone sound system, intake, exhaust, interior LEDs, coilovers, and then the rest.
Despite all of this, I love my car to death and will drive it until then. Looking back, I would've done things differently. Oh well. Lessons learned. After I buy a house, I'll get a second car, and know exactly what I want to do to that one. This one is almost """done."""
