First off what are your tastes? Do you really like the items you listed before?
If you do than go ahead and use them....who care what other people think about your car, unless you are using it to sponser your
company ,Im guessing? go with whats tasteful and flows together well, keep it simple yet stylish, and people will love it. Coming up with a great looking car can take some time, if you really put your head into it!
