I've seen them at Walmart, though I don't ever remember them being sold in colors other than silver/chrome and "actual red". It's not like it's a custom car part.
That looks to me like scratches with dirt.
I'm not complaining about your car. I'm telling you exactly what a collector would say if they were to buy your car (and potentially anyone buying it regularly before the hypothetical classic status). Collectors usually want original everything in impeccable condition. Alternatively, if it's modified, it has to be done in a tasteful and appropriate means- using quality items (I.e. Hot Rods). Making a Daewoo Lanos "sporty" with cheap accessories does not make sense given the context of what the car is. That would be like taking a 1960's MG and making it a RICER, it's a culture clash. Or putting hunting/camo decals, steel bumpers, driving lights, and off-road tires on my 5-series.
You can do whatever you want to your car. Really my only comments I think that should have any weight in your mind are the ones that are said to help you. Those include safety concerns, disaster waiting to happen mechanical problems, and financial decisions- the frequent echoes of "why don't you fix the car before doing x y z."
You have just inadvertantly released this whole can of worms again. You probably don't know, but Matthew doesn't use airbags (let alone need any safety features due to his cat-like reflexes, 360* field of vision, supernatural precognition abilities, advanced professional driving skills, and car's superior driving dynamics).
