I'm New And Need Some Some Answers Please?
 

I just bought a used 03 G35 sedan, it's all pretty stock, but I want to
change that.

So I have some questions? And need some advice?

First of all I would like to know where to find the adapter
to put in a aftermarket standard din size headunit, and is
it possible to use the factory amp and speakers? Mine has
a in dash 6 changer and i was wanting to replace it with a
mp3 possibly video unit, I wanted to utilize the factory speakers
and add in my Orion 10" NT's. (with a separte amp for the subs
of course.

I also need to find some touch up paint for the interior, the interior
door handle on the drivers side has a spot that is black, and my interior
is tan, so is there any way to touch this up?

I wanted to know what the best looking aftermarket driving light
are for the sedan (some opinions) and will I need to drill a hole in the firewall?

I would greatly apreciate some advice thank you in advance.

Also my G35 is a 03 Manual with no navi. or moonroof or rear spoiler
it has 23,000 miles and I paid 21,000 for it last week, did I do ok??
