The bottom number on the oval shaped plate is useful too if you are ever unfortunate enough to have to ask for parts at your local Renault dealer.*
Most GTL parts are still available from Renault if you quote that magic number. (Although the grille would come with the very cool modern Renault badge.)
*A lot of dealers are unhelpful. Whitehouse in Tumbridge Wells make the effort to market themselves as supporters of the older Renaults. Thay'll take credit cards over the phone and post the parts.
