I installed a set on an 05 Jeep GC. The fit was absolutely perfect, but that also is a function of quality labor as well as parts. The color matched perfectly to stock and the custom options were neat too.
All that being said, the surface of the leather wasn't ultra smooth like the really soft (and thin) leather in my wife's Lexus GX and my current landcruiser. The leather was thick and durable, but seemed to be a cheaper cut that had some bumps and texture to it.
I would look at some samples before dropping it in a high end car. For any other application I dont think it can be beat.
