During those early years of Beach manufacture, the pop-top was optional, the internal finish behind the first row was limited, with a lot of bare sheet metal showing around the windows, and only the 2 seat bench was available, which made it really the cheap starter California, light years from today's highly flexible Multivan based vehicle with seating up to 7 and sleeping for four. These days VW has separate assembly lines for the Transporter and the higher finish Multivan which the Beach, Coast and Ocean are based on. It's sad that VW evolved the Beach into a sophisticated version of the California, and then someone at VW who was out of touch and thought it was still an entry level vehicle decided to make it unavailable in the UK.
Edit: on another thread someone has posted the German publicity photo for the four versions of the 6.1 California line. The Beach Camper is advertised as the Beginner's Camper. It looks like a case of the right hand not knowing what the left hand is doing. Someone at VW is responsible for developing the Beach into what it is today, a vehicle which fills a need for a different purpose than the Ocean/Coast, and someone else in marketing is trying to promote a concept of the Beach that VW itself left behind years ago. With this level of unawareness of their own California market, no wonder VW keeps producing a van which has some of the same frustrating design errors as 15 years ago.
