alright
as a fellow 3g owner, im going to give you some constructive criticism
you didnt do that stuff to the car, but heres what i think you should do
get rid of the wing first off, in fact, go outside and do it now, please, it's hideous
If you want a wing, get a stock GT one, I personally think it's the best looking one for our cars
and the blitz bumper is really ugly on our cars, I'd highly recommend changing that out whenever you can afford to, as well as put stock fenders on, if you like the rest of the kit, ( i really have no problem with the rest of it) atleast get rid of the front, and get a different one
I personally think the BCN1 bumper from AIT looks pretty good with that kit
heres some pics of it


but really I'd say get rid of it completely, and go stock, or get the West Wings lip kit if you decide to put the 03-05 bumper on instead of the 00-02 one your car would normally have
but yeah, like what everyone else said keep it clean
and i would recommend using a clay bar and waxing it

But i do have to agree with what a lot of people have said, i wouldn't of payed 8000 for that, no offense or anything, but the value on these cars past 100,000 miles is absolute ****
you do have some good mods it looks like already on the car
but, i got mine,(does have 30k miles more on it)
but counting that, and i dont have as many mods, i still got mine for $3500


but congrats on the new car all things aside and enjoy it, they are great cars and fun to drive too, I've had mine for almost 4 months now and im still loving it

oh and one last thing i forgot, there is supposed to be a black plastic piece on your hatch, i would try to find one from somebody parting there's out or a junkyard, and if you can, build a better box for those subs
