The last suggestion from spikey helped a lot, and helps defining more shapes for the car.
I also added some “chrome line”, desperately trying to give more character to the car. 
I think it’s going somewhere… I don’t know where but I’m curious to find out.
And I know it’s way too early for that, but since I didn’t feel like doing much more modeling this evening, I spent a few minutes messing around with shader…
