Additional costs for anthracite for windows, front door, and garage door?

For us, white and anthracite were standard. Now we have anthracite on the outside and white on the inside at no extra cost.

we also have plastic, anthracite foil on the outside. We had this included in the first offer right away, but according to the site manager, the additional cost is "hardly relevant".

We paid 2,600 for all windows and the front door with side panel. The garage door cost an additional 350.

This is now ordered so frequently by some manufacturers of plastic windows that you almost have to say the other way around: without foiling is not a lower price.
