I think you're being offering a good deal.

I have this product on the ML500. I have it 14 inches on the hood, all of the front bumper, and both mirrors. I paid $800 Canadian for this...which is roughly 550 Euros.

Granted the ML500 is a sandy color, so you won't see it at all. I think on dark cars you might see the line easier, but this thing serves its purpose very well in my opinion.
