Hi Mark - my first posting!
My spec sounds similar to yours - Ocean 204 4M, traction control, diff lock, towbar, other bits and pieces. So am now following progress with your order with interest especially re price protection.
I ordered mid August 2021, had no updates at all (except the VW standard delays letter x2) until 30 July when my dealer told me it had now been ‘accepted by the factory’ with a ‘build date’ of week 35, which is next week (first week in September) so if thats still correct and based on other reports on here I am assuming delivery in October...maybe.
Nothing has ever been mentioned ref price increase/protection and I am hoping that once its being built to order that that will not arise…but I note what others have pointed out that the small print of the T&C would allow a price increase to be passed on. I don't believe they were given to me when I signed the order though. I don't propose to ask but I too would have an almighty row if that was now proposed since it looks like it will be 14 months from order.
Good luck with your build and will be interested in further updates, I will provide mine too.
