I can't help with the your discount question as both of ours were also demos. It's a great way of buying a Cali if you can find one with the right spec. It's possible to get a much larger discount and there aren't really any dis-advantages of buying this way either.
Regarding your TV/DVD enquiry, I recently volunteered to test a new TV bracket that Comfortz Leisure were adverting. I believe you can now get these from Comfortz via the club shop. This was my review:
We have a small Avtex 18" TV/DVD with an Avtex STH 3000 digital aerial, that gets occasional use on long dark evenings in the Cali. The trouble is that we usually stand it on the cooker/sink worktop and this makes it awkward if you want to use the facilities beneath at the same time. Could this new TV bracket be the answer?
Well we have just tested it and can report that it does exactly what it says on the tin. This multi component black metal bracket is comprised of two main sub assemblies, the first being the section that fits onto the seat headrest and the second is the bracket that is secured to the rear of the TV. It is compact, well made and fits securely, facing rearwards, onto the chrome headrest supports on the passenger seat. Here it is fitted and with the section that joins to the other half of the bracket (screwed to the rear of the TV) folded away for safety. The bracket is a little fiddly to fit but once fitted can remain in situ permanently.
It is possible to view the TV/DVD with the seat facing forward........
or by removing the headrest and reversing it you can view with the seat facing rearwards.
Once the bracket (shown above) is fitted to the headrest, all you have to do is permenantly screw the other half of the bracket to the standard fixing holes on the rear of your TV with the screws provided and its ready to be attached. This is a simple matter of joining the TV with bracket attached to the other half on the headrest with the bolt and wingnut provided. Then adjust the angle to suit and tighten. Simples!
So far we have only used the TV two or three times but on each occasion we have found the reception to be excellent just by hanging our aerial internally inside the pop top roof.
When not in use, our TV/DVD sits safely inside it's Avtex case behind the passenger seat.
So to conclude, this is a very neat and well made bracket that holds the TV firmly in place. It enables you to free up the worktop space and places your TV/DVD in a good viewing location. It's brilliant! What more is there to say?
We have had this Cali for sixteen months and used the TV only about four times!
