Why thank you d W124.
I have to say I don't like to modify cars from standard but I have been looking at new Mercs and I have to say I like the lighter colour leathers used on the seats, and the stitching on the dash & console.
The problem when you see this type of thing on older cars is that it is seldom done properly. Either the stitching is too large with too course a thread or the leather is too thick and looks like a fat rendition of what we have at the moment. The ad looked like you could order a custom job - be nice to see it done really well with fine materials, it could be worth it if you were removing the dash in any case, especially if you had a damaged or cracked dash!
