Interesting - I think a lot of assumptions being made on behalf of others, based on personal viewpoints (in my opinion! ...)
I wouldn't be so bold as to put a number on it, but 'many people' do not want to become part-time volunteer Camper Market Analysts, have any idea at all as to the effect of VED changes, or will be remotely put off California ownership by potential roof corrosion (I've not read the T6 thread or popped my own top since).
As for specs, if I've learned anything from these forums it's the vast range of preferences & use-cases - there is no 'best', it's all horses for courses. I'm personally delighted with my Acapulco Blue Beach as above & hadn't the least interest in "removable tow bar, 3 zone climatronic aircon, tinted windows, heated screen, fogs, mfsr, top end satnav/radio, seven seats including intagrated child seats [or] a whole lot else besides".
I did however want DSG and sprang extra for a retrofit aux heater & wish the dipped headlamps were a little brighter... As for how much it's worth now or whether anyone else wants to buy one? - nope, not a care, each to their own ...
