The upper back seat of my 2005 g35 coupe was broken into and the leather upholstery was cut up and damaged so I wanted to know what my options were for fixing it.

I wanted to know if I swap out the rear upper back seat of my 2005 coupe with one from a 2003 model, will I notice the difference?

Also I purchased the wrong color interior from another 2005 model so I have a replacement upper back seat but its the wrong color and doesn't match the interior. What ideas do you guys have i could do with that. There isn't much of a demand so its been difficult to resell it.
