Changing the color of a 2002 Mercedes Benz E320 is easy. The car’s interior is black with a woodgrain pattern. The leather seats, door handles, and dash are leather. The upholstery has to be re-upholstered to protect it from wear and tear. This can be a big job, but if you do it right, the color will last for years to come. The leather is very durable, and the manufacturer provides several colors to choose from.
