I used to own WXL 28. I bought it from an old guy in a village south of Derby sometime in the early 1990's and kept it for several years. It had been restored when I bought it and had good quality, but non standard, upholstery and carpets. I believe that the engine had been rebuilt. It had been repainted in the original Diamond Green metallic and had later front wing top indicators. As far as I can remember the guy I bought it from had aquired it from the widow of the previous owner who had some connection with an independent VW garage in Derby. I can't remember who I sold it to but I haven't seen it at any VW shows for many years now.
Cheers Rob.
