I have recently acquired a 405 SD V8 on a 2013 plate. Basic colour is black with gray/silvery fin like side panels going upwards (I don’t know the technical name!) with similar colour panel next to windscreen wipers. They are a bit tatty and I would like to refurbish them. Similarly, the leather on the driver’s seat is showing the wear to be expected at 150,000 miles. I would like some help where I can get these items refurbished. The car is fantastic and I would like to bring it back to its former glory
