Perfect, I feel honored.

"Modified their logo" is an understatement. You rotated it. And thats not inspiration, thats taking. Also, must have not tried very hard to make arrow designes cause I just whipped this up in photoshop in a few seconds and I think it looks just fine, without being a Citreon copy:

I really don't like how you are just using Citroën's logo, but put it sideways. I suggest being more creative and making your own.
