I agree 100%. The default Lexus "skin" would be very easy to duplicate, as Justin has done (I seriously doubt he got "permission" form Lexus to copy their GUI). As far as graphics, All that is needed is a background, and about 4 differnet button sizes, that are simple PhotoShop bevels. Then placing text/icons on the buttons.
Anyone with just very basic photoshop skils could duplicate the look of that skin easily. Then you could decide on what colors to use from scratch.
