Suggestion:
Your post reflects that you have keen interest in CIVIC, Same as I was in PK......................
Some suggestion for your car, hopefully you would like it.
1- Projector Lights: Light for doors, when it will open! a monogram or image as you like will glow on road.
2- Lazer Line. A line will draw on the road in front/back of car for distance warning. (It is very hard to find it)
3- Electronic tint glass paper. This is electronic paper for car windows to make it dark, Light or transparent glass(adjustable knob). I saw video but don't know where to find it.
4- Electric back mirror. Available in Honda accord. Better is use GMC back mirror, it comes with video screen(for Back camera), Temperature value and dim at high beam.
OTHER IDEAS I WILL SHARE WITH YOU.
