Photoshop help please - carpet change

[Zippee]

Hi all,

Just wandering if any kind PHers with photoshop skills could help me. I'm looking to get my T350 re-carpeted as they are currently filthy and quite tatty looking (Pic below is old). Currently they are light grey as below;



However, I'm considering a colour change to anthracite/dark grey with red piping as per this Sag but am wanting to get a rough idea as to how it will look , especially with the grey leather flashes on the dash and seats;




Last thing I want to do is splash out several hundred punds only for it to look totally wrong against the rest of the interior. Any other colour option suggestions would also be welcomed. Thanks in advance.
