My all-black car looks a bit boring.

Never been into graphics before, but am wondering how some graphics might change the look. I am thinking of something simple and clean, and would appreciate some feedback on the ideas below.
1) A simple graphic down the side, along the lines of the classic Porsche style (obviously it wouldn’t say Porsche or Turbo):

2) I think blue and red would look good on a black car, and have always liked the vintage Datsun livery:

I’m thinking maybe taking those red and blue stripes and running them down the fender on one side or maybe both.
Anyone have any ideas or opinions? Thanks!
