I don't know if it's relevant or where you are (apologies if it's not relevant), I very recently traded a T6 Caravelle for our first California. I'd kept an eye on Caravelle prices but had obviously got mixed up with potential private prices rather than trade in, and was horrified when I got the price from the valuation websites. I ended up getting our California from an independent specialist near Penrith, and they were absolutely brilliant. I'm not a negotiator, and they gave a very fair price for the Caravelle and prepped the California brilliantly. They had a number of cars for sale, and seemed to be open to sourcing something if they didn't have what you wanted. They may therefore be able to find you an A6, or indeed a Beach. Sorry if that's a bit much, but I'd have been grateful for the recommendation when I was looking so hope it's ok to suggest it. Garage is called Braithwaites.
