Yeah, I'll be happy with an all beige interior. I even thought about doing a color change to camel in order to have a little darker tone for some contrast but still keeping it on the same color range.
Now, the risk there is that since the green is such a dark color that coverage would be more difficult. Like I said before, some go to a white base first and then the actual color.
The challenge with getting new seats is how expensive it is adding €500/600 euros of shipping alone which is both ridiculous and understandable at the same time due to the size/weight of the seats and the distance.
Lovely Z by the way!
